To rein in that speed, a massive set of continuous-weave carbon-ceramic brake rotors from Alcon (option code J59) measure 16.5 inches (420 mm) in diameter, front and rear, clamped down by GM’s first-ever 10-piston calipers. At the Nurburgring’s Tiergarten corner, those brakes managed to haul down the ZR1X at a peak of 1.9 G decel from 180 to 120 mph (290 to 193 km/h).

The AWD isn’t all about straightline speed, however, and the ZR1X can reportedly handle 1 G of lateral and longitudinal acceleration while cornering—simultaneously. Yet the ZR1X should add around the same weight as the E-Ray versus the Z51 Stingray, which rounded out to just shy of 500 pounds (227 kg). For comparison, the ZR1’s official dry weight is 3,670 pounds (1,665 kg) but with 13 radiators supporting a massively capable cooling system, the wet weight likely approaches 4,000 lbs (1,814 kg).

Similarly, the ZR1X will also be available as both a removable hardtop coupe and a powered hardtop convertible—meaning that in its heaviest guise, this American hypercar might push up to nearly 5,000 pounds (2,268 kg).

Even without confirmed pricing, the ZR1X clearly takes a swing at Ferrari’s F80, McLaren’s W1, and Porsche’s highly anticipated but as-yet-unconfirmed next-gen hypercar—and likely at a mere fraction of the cost, given the ZR1’s $174,995 MSRP. However, even though Chief Engineer Josh Holder called this “the most intelligent Corvette ever,” he also owned up to the challenges of cramming 2.5 times the horsepower of the Z51 Stingray into the same chassis.

Developing the ZR1X therefore required refinements to the E-Ray’s software, welcome news after that earlier hybrid variant exhibited some strange behavior almost akin to reverse torque steer due to the front-axle regen programming, plus difficulties handling high-performance loads in anything less than perfect conditions—which occasionally even resulted in the computer fully disconnecting the front axle and switching off the front motor.

Everything we know about the 2026 Nissan Leaf

The first-generation Nissan Leaf was an incredible achievement for the company and for the industry. A mass-market EV that wasn’t priced out of reach was something the industry needed at the time.

That’s important. Since then, things have stagnated. To say that the 2026 Leaf is the most important EV launch for Nissan since the original car would be an understatement. It must get it right, because the competition is too good not to.

Starting things off, the car is available with two battery options. There is a 52 kWh base pack and a 75 kWh longer-range option. Each option has an active thermal management system—a first for Leaf—to address DC fast-charging concerns. Those batteries also deliver more range, with up to 303 miles (488 km) on the S+ model.

The 2026 Leaf is 3 inches shorter (76 mm) than the current hatchback, although the wheelbase is only 0.4 inches (10 mm) shorter. Nissan

The 52-kWh version makes 174 hp (130 kW), and the 75-kWh motor generates 215 hp (160 kW).

The Leaf adopts Nissan’s new 3-in-1 EV powertrain, which integrates the motor, inverter, and reducer. This reduces packaging by 10 percent, and Nissan claims it improves responsiveness and refines the powertrain.

Native NACS

Instead of a slow and clunky CHAdeMO connector, the Leaf rocks a Tesla-style NACS port for DC fast charging. Interestingly, the car also has a SAE J-1772 connector for AC charging. The driver’s side fender has the J plug, while the passenger side fender has the NACS.

Confusingly, the NACS connector is only for DC fast charging. If you’re going to level 2 charge, you must use the J plug or a NACS connector with an adapter. It’s weird, but the car will make it obvious to owners if they plug into the wrong connector.

When connected to a DC fast charger that can deliver 150 kW, both battery sizes will charge from 10 to 80 percent in 35 minutes. While not class-leading, it wipes the floor with the old model. It also supports a peak charging rate that is higher than its bigger sibling, the Ariya.

rtfb:-the-raise-act

RTFB: The RAISE Act

The RAISE Act has overwhelmingly passed the New York Assembly (95-0 among Democrats and 24-22 among Republicans) and New York Senate (37-1 among Democrats, 21-0 among Republicans).

Governor Kathy Hochul now has to decide whether or not to sign it, which she has 10 non-Sunday days to do once the bill is delivered (30 if they’re out of session), but the bill might not be delivered for six months.

The aim of this post, now that we are seeing increasing public discussion, is to go through the bill to understand exactly what the bill would and would not do.

The RAISE Act is centrally a transparency bill. It requires frontier model developers to maintain, publish and adhere to (one might say ‘open source’ except that they can redact details for various reasons) a safety and security protocol (SSP) that outlines how they will, before releasing their frontier models, take appropriate steps to reduce risk of critical harm (100 casualties or 1 billion in damages) caused or materially enabled by those models. It must designate senior people as responsible for implementation.

It also requires companies to disclose (as in, write two sentences informing us about) safety incidents within 72 hours.

Enforcement is done only by the attorney general, and limited to injunctive or declaratory relief and fines of a maximum of $10 million for the first violation and $30 million for subsequent violations. This can happen if a company fails to take appropriate preventative steps, even if no critical harm has yet resulted, so if the SSP proves sufficiently inadequate preemptive action can be taken.

My take on the RAISE Act is that it seems clearly to be bending over backwards to avoid imposing substantial costs on the companies involved even if the state were to attempt to enforce it maximally and perversely, to give those companies maximum flexibility in how they respond, and to only apply to a handful of major players.

The bill is thus insufficient on its own but an important improvement upon the status quo. I strongly support this bill. I am very much not alone. The RAISE Act is a highly popular bill, supported (with admittedly very low salience) by 84% of New Yorkers.

a16z has already attempted to kill this bill before it overwhelmingly passed both houses, circulating an opposition memo and reportedly calling members. We should expect a continued flurry of industry lobbying against RAISE, likely following the usual playbooks, and for them to greatly outspend bill advocates.

o3-pro thinks Hochul is likely to ultimately sign the bill. with a 65% chance it becomes law in current form, 15% chance it becomes law with negotiated chapter amendments. The Manifold market has a 57% chance that the bill becomes law.

There are two big advantages we have in reading the RAISE Act.

  1. It is short and simple.

  2. We’ve analyzed similar things before.

Relax. This will be a breeze.

The bill is mostly definitions.

These are mostly standard. The AI definition has been consistent for a while. Compute cost is defined as the published market price cost of cloud compute, as reasonably assessed by the person doing the training, which is as clear and generous as one could hope.

The most important definition is ‘frontier model’:

6. “Frontier model” means either of the following:

(a) an artificial intelligence model trained using greater than 10^26 computational operations (e.g., integer or floating-point operations), the compute cost of which exceeds one hundred million dollars;

OR

(b) an artificial intelligence model produced by applying knowledge distillation to a frontier model as defined in paragraph (a) of this subdivision, provided that the compute cost for such model produced by applying knowledge distillation exceeds five million dollars.

The first provision will centrally be ‘you spent $100 million dollars.’ Which remains a lot of dollars, and means this will only apply to a handful of frontier labs. But also note that 10^26 will for a while remain a lot of FLOPS. Epoch looked at this question, and also estimates the costs of various models, with the only current model over 10^26 likely being Grok 3 (o3-pro suggests it is not impossible that Gemini Ultra or a few others might just barely also qualify, although I find this highly unlikely).

The question is the second provision. How often will companies make distillations that cost more than $5 million and result in ‘similar or equivalent capabilities’ to the original, as required by the definition of distillation used here?

o3-pro believes the current number of such models, even without considering the capabilities requirement, is probably zero (the possible exception is Claude Haiku, if you think it has sufficiently comparable capabilities). It anticipates the number of $5 million distillations will not remain zero, and expects the distillations to mostly (but not entirely) be from the same companies releasing the $100 million frontier models.

Its baseline scenario is by 2029, there will be ~6 American frontier-trainers, in particular OpenAI, DeepMind, Anthropic, Meta, xAI and then maybe Amazon or Apple or perhaps an open source collective, and ~6 more distillers on top of that passing the $5 mark, starting with Cohere, then maybe Databricks or Perplexity.

A ‘large developer’ means spending a combined $100 million in training compute, or someone who buys the full intellectual rights to the results of that, with academic institutions doing research excluded.

This bill would have zero impact on everyone else.

So yes, there will be talk about how this will be ‘more difficult’ for ‘smaller’ companies. But by ‘smaller’ companies we mean a handful of large companies, and by ‘more difficult’ we mean a tiny fraction of overall costs. And as always, please point to the thing that you would have to do, that you don’t think is worth doing, or is even a substantial impact on their business costs?

Bill opponents, of course, are telling the same lies about this they told about SB 1047. Brianna January of the ‘Chamber of Progress’ calls this ‘an eviction notice for New York’s 9,000 AI startups,’ saying it ‘would send AI innovators packing,’ when exactly zero of these 9,000 startups would have to lift a single finger in response to this bill.

This is pure bad faith Obvious Nonsense, and you should treat anyone who says similar things accordingly. (The other Obvious Nonsense claim here is that the bill was ‘rushed’ and lacked a public hearing. The bill very much followed normal procedures and had debate on the floor, the bill was in the public pipeline for months, and bills in New York do not otherwise get pubic hearings, that’s a non sequitur.)

“Critical harm” means the death or serious injury of one hundred or more people or at least one billion dollars of damages to rights in money or property caused or materially enabled by a large developer’s use, storage, or release of a frontier model, through either of the following:

(a) The creation or use of a chemical, biological, radiological, or nuclear weapon; or

(b) An artificial intelligence model engaging in conduct that does both of the following:

(i) Acts with no meaningful human intervention; and

(ii) Would, if committed by a human, constitute a crime specified in the penal law that requires intent, recklessness, or gross negligence, or the solicitation or aiding and abetting of such a crime.

A harm inflicted by an intervening human actor shall not be deemed to result from a developer’s activities unless such activities were a substantial factor in bringing about the harm, the intervening human actor’s conduct was reasonably foreseeable as a probable consequence of the developer’s activities, and could have been reasonably prevented or mitigated through alternative design, or security measures, or safety protocols.

We have ‘caused or materially enabled’ and also ‘substantial factor’ and ‘harm that mitigations could have reasonably prevented’ and either 100 serious injuries or a billion dollars in damage as the thresholds, and either the act has to be autonomous, be a CBRN risk, or constitute a crime in the penal law.

That seems like a robust way of saying ‘if you trigger this provision you screwed up?’

They have to be reported, so what exactly are they?

“Safety incident” means a known incidence of critical harm

OR an incident of the following kinds that occurs in such a way that it provides demonstrable evidence of an increased risk of critical harm:

  1. A frontier model autonomously engaging in behavior other than at the request of a user;

  2. Theft, misappropriation, malicious use, inadvertent release, unauthorized access, or escape of the model weights of a frontier model;

  3. The critical failure of any technical or administrative controls, including controls limiting the ability to modify a frontier model;

  4. Unauthorized use of a frontier model.

The incidence of an actual critical harm is clear.

The second half of the definition has two halves.

  1. It has to involve one of the four things listed.

  2. It has to provide demonstrable evidence of an increased risk of critical harm.

As in, something in your safety protocols goes wrong, in a way that makes you more worried about risk. That seems like the kind of thing you should report. I will be very happy to see these systematically written down, and even happier to have them disclosed.

As in, within 72 hours of any safety incidents, you have to notify the attorney general and DHSES. This is the common standard used for cybersecurity breaches. You have to include:

  1. The date of the incident.

  2. Why it qualifies as a safety incident.

  3. ‘A short and plain statement describing the safety incident.’

Does this, as some have suggested, constitute such a burden that it interferes with the ability to respond to the incident? That seems difficult to believe.

For example, you could write ‘On Tuesday, June 17, 2025, someone gained unauthorized access to our frontier model. This makes us more worried about future unauthorized access.’ That’s it.

I have no sympathy for the claim that asking for that style of statement within three days is a distracting or undue burden that outweighs our right to know, or its costs exceed benefits. In many cases, waiting longer could have serious repercussions.

What are we actually asking companies to produce, exactly? A documentation and description of technical and organizational protocols that if fully implemented would:

  1. ‘Appropriately reduce the risk of critical harm.’

  2. ‘Appropriately reduce the risk of’ unauthorized access to or misuse of the model weights ‘leading to critical harm.’

  3. Describe a detailed test procedure to evaluate potential misuse or loss of control or combination with other software to potentially cause critical harm.

  4. Enable compliance with this article.

  5. Designate senior personnel to be responsible for ensuring compliance.

This requires ‘detailed test procedures’ to be described in advance, which seems like a very good idea, and does not preclude additional tests. The rest seems so basic that it seems laughable to object to being told to do any of it.

Before deploying (meaning externally, as in giving a third party access) to a frontier model, the developer must write and implement an SSP, retain an up-to-date copy of that SSP, conspicuously publish a redacted copy of the SSP, give the attorney general and DHSES access upon request to the full SSP and retain copies of all your test results sufficient to allow third-party replication.

As always, there are no specific requirements for the SSP, other than that it must ‘appropriately reduce the risk’ of critical harms, both directly or through unauthorized access, and that it spell out your testing procedure, and that you actually have someone ensure you use it. If you want to write the classic ‘lol we’re Meta, we don’t run tests, full open weights release without them seems appropriate, I’m sure it will be fine’ you can do that, although you might not like what happens when people notice you did that, or when the risks materialize, or potentially the AG notices you’re not taking the appropriate actions and sues you.

You need to conduct an annual review of the SSP to adjust for increased model capabilities, and make and publish any appropriate adjustments. Seems wise.

I for one think that if your model would create an unreasonable risk of critical harm then that means you shouldn’t release it. But that’s just me.

Again, yeah, I mean, I hope that stands to reason.

The attorney general can bring a civil action with penalties of:

  1. $10 million for the first violation, $30 million for additional ones.

  2. Injunctive or declaratory relief.

And that’s it. Explicitly no private right of action, no limit of the application of other laws, everything is cumulative with other requirements. If you cause an incident that costs billions of dollars, your fines don’t scale with that.

I don’t see any clause allowing compensatory relief. So if there’s a violation related to an actual critical harm, I presume any fines involved will be the least of your problems.

The main actual consequences are that frontier labs will be forced to be transparent about their safety and security protocols (SSPs) and what tests they intend to run and other precautions they intend to take, in order to guard against critical harms. Most labs impacted already do this, and will only have to newly include the evals they intend to run. Publishing these details will allow us to critique them, and apply pressure to create better protocols.

Again, while I have concerns that the bill is insufficient strong, I think all of this is a very good thing. I strongly support the bill.

F1 in Canada: Well, that crash was bound to happen

Russell led from the start and kept Verstappen in check throughout the race until the thing McLaren has surely been dreading all year happened. Thanks to pit strategy, Norris had moved up the running order and was in fifth place, trying to pass Piastri for fourth. After thinking better of it at the hairpin at the far end of the circuit, Norris thought he saw an opportunity going into turn 1. Instead, he misjudged things, and the gap disappeared. His front wing met Piastri’s rear tire, his car’s left side met the concrete wall, and his day was done.

With two such closely matched drivers in equal machinery, a collision on track was bound to occur. As McLaren teammate collisions go, this one lacked the near-hatred of Prost versus Senna and didn’t cost it a win in the process. Now that it’s out of the way, hopefully the kids won’t do it again.

Norris’ crash brought out a safety car, which remained in effect for the final few laps of the race. So little happened during the race that the highlight reel that plays in the green room post-race was over almost before it started.

MONTREAL, QUEBEC - JUNE 15: Lando Norris of Great Britain and McLaren walks away after a crash during the F1 Grand Prix of Canada at Circuit Gilles-Villeneuve on June 15, 2025 in Montreal, Quebec.

It’s all getting a bit aggro

The off-track action has been far more vicious, with two big stories dominating the buildup to the Grand Prix. The first was Verstappen’s penalty points: Accumulate 12 points in 12 months, and the result is a one-race ban. Verstappen is currently on 11 points following his collision with Russell in Spain, so any slip-up that earns him a penalty point will send Red Bull scrambling to find enough drivers to fill all four of its cars (two Red Bulls, two RBs), should the reigning world champion get benched.

These VA Tech scientists are building a better fog harp

Unlike standard fog harvesting technologies, “We’re trying to use clever geometric designs in place of chemistry,” Boreyko told Ars. “When I first came into this field, virtually everyone was using nets, but they were just trying to make more and more clever chemical coatings to put on the nets to try to reduce the clogging. We found that simply going from a net to a harp, with no chemicals or coatings whatsoever—just the change in geometry solved the clogging problem much better.”

For their scale prototypes in the lab, Boreyko’s team 3D printed their harp “strings” out of a weakly hydrophobic plastic. “But in general, the harp works fantastic with uncoated stainless steel wires and definitely doesn’t require any kind of fancy coating,” said Boreyko. And the hybrid harp can be scaled up with relative ease, just like classic nets. It just means stringing together a bunch of harps of smaller heights, meter by meter, to get the desired size. “There is no limit to how big this thing could be,” he said.

Scaling up the model is the next obvious step, along with testing larger prototypes outdoors. Boreyko would also like to test an electric version of the hybrid fog harp. “If you apply a voltage, it turns out you can catch even more water,” he said. “Because our hybrid’s non-clogging, you can have the best of both worlds: using an electric field to boost the harvesting amount in real-life systems and at the same time preventing clogging.”

While the hybrid fog harp is well-suited for harvesting water in any coastal region that receives a lot of fog, Boreyko also envisions other, less obvious potential applications for high-efficiency fog harvesters, such as roadways, highways, or airport landing strips that are prone to fog that can pose safety hazards. “There’s even industrial chemical supply manufacturers creating things like pressurized nitrogen gas,” he said. “The process cools the surrounding air into an ice fog that can drift across the street and wreak havoc on city blocks.”

smart-tires-will-report-on-the-health-of-roads-in-new-pilot-program

Smart tires will report on the health of roads in new pilot program

Do you remember the Pirelli Cyber Tire? No, it’s not an angular nightmare clad in stainless steel. Rather, it’s a sensor-equipped tire that can inform the car it’s fitted to what’s happening, both with the tire itself and the road it’s passing over. The technology has slowly been making its way into the real world, starting with rarified stuff like the McLaren Artura. Now, Pirelli is going to put some Cyber Tires to work for everybody, not just supercar drivers, in a new pilot program with the regional government of Apulia in Italy.

The Cyber Tire has a sensor to monitor temperature and pressure, using Bluetooth Low Energy to communicate with the car. The electronics are able to withstand more than 3,500 G as part of life on the road, and a 0.3-oz (10 g) battery keeps everything running for the life of the tire.

The idea was to develop a better tire pressure monitoring system, one that could tell the car exactly what kind of tire—summer, winter, all-season, and so on—was fitted, and even its state of wear, allowing the car to adapt its settings appropriately. But other applications suggested themselves—at a recent CES, Pirelli showed how a Cyber Tire could warn other road users about aquaplaning. Then again, we’ve been waiting more than a decade for vehicle-to-vehicle communication to make a difference in daily driving to no avail.

Apulia’s program does not rely on crowdsourcing data from Cyber Tires fitted to private vehicles. Regardless of the privacy implications, the rubber isn’t nearly in widespread enough use for there to be a sufficient population of Cyber Tire-shod cars in the region. Instead, Pirelli will fit the tires to a fleet of vehicles supplied by the fleet management and rental company Ayvens. Driving around, the sensors in the tires will be able to infer how rough or irregular the asphalt is, via some clever algorithms.

“yuck”:-wikipedia-pauses-ai-summaries-after-editor-revolt

“Yuck”: Wikipedia pauses AI summaries after editor revolt

Generative AI is permeating the Internet, with chatbots and AI summaries popping up faster than we can keep track. Even Wikipedia, the vast repository of knowledge famously maintained by an army of volunteer human editors, is looking to add robots to the mix. The site began testing AI summaries in some articles over the past week, but the project has been frozen after editors voiced their opinions. And that opinion is: “yuck.”

The seeds of this project were planted at Wikimedia’s 2024 conference, where foundation representatives and editors discussed how AI could advance Wikipedia’s mission. The wiki on the so-called “Simple Article Summaries” notes that the editors who participated in the discussion believed the summaries could improve learning on Wikipedia.

According to 404 Media, Wikipedia announced the opt-in AI pilot on June 2, which was set to run for two weeks on the mobile version of the site. The summaries appeared at the top of select articles in a collapsed form. Users had to tap to expand and read the full summary. The AI text also included a highlighted “Unverified” badge.

Feedback from the larger community of editors was immediate and harsh. Some of the first comments were simply “yuck,” with others calling the addition of AI a “ghastly idea” and “PR hype stunt.”

Others expounded on the issues with adding AI to Wikipedia, citing a potential loss of trust in the site. Editors work together to ensure articles are accurate, featuring verifiable information and a neutral point of view. However, nothing is certain when you put generative AI in the driver’s seat. “I feel like people seriously underestimate the brand risk this sort of thing has,” said one editor. “Wikipedia’s brand is reliability, traceability of changes, and ‘anyone can fix it.’ AI is the opposite of these things.”

trade-war-truce-between-us-and-china-is-back-on

Trade war truce between US and China is back on

Both countries agreed in Geneva last month to slash their respective tariffs by 115 percentage points and provided a 90-day window to resolve the trade war.

But the ceasefire came under pressure after Washington accused Beijing of reneging on an agreement to speed up the export of rare earths, while China criticized new US export controls.

This week’s talks to resolve the impasse were held in the historic Lancaster House mansion in central London, a short walk from Buckingham Palace, which was provided by the British government as a neutral ground for the talks.

Over the two days, the US team, which included Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick, and US trade representative Jamieson Greer, [met with] the Chinese delegation, which was led by He Lifeng, a vice-premier responsible for the economy.

The negotiations were launched to ensure Chinese exports of rare earths to the US and American technology export controls on China did not derail broader talks between the sides.

Ahead of the first round of talks in Geneva, Bessent had warned that the high level of mutual tariffs had amounted to an effective embargo on bilateral trade.

Chinese exports to the US fell more steeply in May compared with a year earlier than at any point since the pandemic in 2020.

The US had said China was not honoring its pledge in Geneva to ease restrictions on rare earths exports, which are critical to the defense, car, and tech industries, and was dragging its feet over approving licenses for shipments, affecting manufacturing supply chains in the US and Europe.

Beijing has accused the US of “seriously violating” the Geneva agreement after it announced new restrictions on sales of chip design software to Chinese companies.

It has also objected to the US issuing new warnings on the global use of Huawei chips and canceling visas for Chinese students.

Separately, a US federal appeals court on Tuesday allowed some of Trump’s broadest tariffs to remain in place while it reviews a lower-court ruling that had blocked his “liberation day” levies on US trading partners.

The ruling extended an earlier temporary reprieve and will allow Trump to enact the measures as well as separate levies targeting Mexico, Canada, and China. The president has, however, already paused the wider “reciprocal” tariffs for 90 days.

Bill Atkinson, architect of the Mac’s graphical soul, dies at 74

Using HyperCard, Teachers created interactive lessons, artists built multimedia experiences, and businesses developed custom database applications—all without writing traditional code. The hypermedia environment also had a huge impact on gaming: 1993 first-person adventure hit Myst originally used HyperCard as its game engine.

For the two-color Macintosh (which could only display black or white pixels, with no gradient in between), Atkinson developed an innovative high-contrast dithering algorithm that created the illusion of grayscale images with a characteristic stippled appearance that became synonymous with early Mac graphics. The dithered aesthetic remains popular today among some digital artists and indie game makers, with modern tools like this web converter that allows anyone to transform photos into the classic Atkinson dither style.

Life after Apple

After leaving Apple in 1990, Atkinson co-founded General Magic with Marc Porat and Andy Hertzfeld, attempting to create personal communicators before smartphones existed. Wikipedia notes that in 2007, he joined Numenta, an AI startup, declaring their work on machine intelligence “more fundamentally important to society than the personal computer and the rise of the Internet.”

In his later years, Atkinson pursued nature photography with the same artistry he’d brought to programming. His 2004 book “Within the Stone” featured close-up images of polished rocks that revealed hidden worlds of color and pattern.

Atkinson announced his pancreatic cancer diagnosis in November 2024, writing on Facebook that he had “already led an amazing and wonderful life.” The same disease claimed his friend and collaborator Steve Jobs in 2011.

Given Atkinson’s deep contributions to Apple history, it’s not surprising that Jobs’ successor, Apple CEO Tim Cook, paid tribute to the Mac’s original graphics guru on X on Saturday. “We are deeply saddened by the passing of Bill Atkinson,” Cook wrote. “He was a true visionary whose creativity, heart, and groundbreaking work on the Mac will forever inspire us.”

Ex-FCC Chair Ajit Pai is now a wireless lobbyist—and enemy of cable companies


Pai’s return as CTIA lobbyist fuels industry-wide battle over spectrum rights.

Ajit Pai is back on the telecom policy scene as chief lobbyist for the mobile industry, and he has quickly managed to anger a coalition that includes both cable companies and consumer advocates.

Pai was the Federal Communications Commission chairman during President Trump’s first term and then spent several years at private equity firm Searchlight Capital. He changed jobs in April, becoming the president and CEO of wireless industry lobby group CTIA. Shortly after, he visited the White House to discuss wireless industry priorities and had a meeting with Brendan Carr, the current FCC chairman who was part of Pai’s Republican majority at the FCC from 2017 to 2021.

Pai’s new job isn’t surprising. He was once a lawyer for Verizon, and it’s not uncommon for FCC chairs and commissioners to be lobbyists before or after terms in government.

Pai’s move to CTIA means he is now battling a variety of industry players and advocacy groups over the allocation of spectrum. As always, wireless companies AT&T, Verizon, and T-Mobile want more spectrum and the exclusive rights to use it. The fight puts Pai at odds with the cable industry that cheered his many deregulatory actions when he led the FCC.

Pai wrote a May 4 op-ed in The Wall Street Journal arguing that China is surging ahead of the US in 5G deployment and that “the US doesn’t even have enough licensed spectrum available to keep up with expected consumer demand.” He said that Congress must restore the FCC’s lapsed authority to auction spectrum licenses, and auction off “at least 600 megahertz of midband spectrum for future 5G services.”

“During the first Trump administration, the US was determined to lead the world in wireless innovation—and by 2021 it did,” Pai wrote. “But that urgency and sense of purpose have diminished. With Mr. Trump’s leadership, we can rediscover both.”

Pai’s op-ed drew a quick rebuke from a group called Spectrum for the Future, which alleged that Pai mangled the facts.

“Mr. Pai’s arguments are wrong on the facts—and wrong on how to accelerate America’s global wireless leadership,” the vaguely named group said in a May 8 press release that accused Pai of “stunning hypocrisy.” Spectrum for the Future said Pai is wrong about the existence of a spectrum shortage, wrong about how much money a spectrum auction could raise, and wrong about the cost of reallocating spectrum from the military to mobile companies.

“Mr. Pai attributes the US losing its lead in 5G availability to the FCC’s lapsed spectrum auction authority. He’d be more accurate to blame his own members’ failure to build out their networks,” the group said.

Big Cable finds allies

Pai’s op-ed said that auctioning 600 MHz “could raise as much as $200 billion” to support other US government priorities. Spectrum for the Future called this an “absurd claim” that “presumes that this auction of 600 MHz could approach the combined total ($233 billion) that has been raised by every prior spectrum auction (totaling nearly 6 GHz of bandwidth) in US history combined.”

The group also said Pai “completely ignores the immense cost to taxpayers to relocate incumbent military and intelligence systems out of the bands CTIA covets for its own use.” Spectrum for the Future didn’t mention that one of the previous auctions, for the 3.7–3.98 GHz band, netted over $81 billion in winning bids.

So who is behind Spectrum for the Future? The group’s website lists 18 members , including the biggest players in the cable industry. Comcast, Charter, Cox, and lobby group NCTA-The Internet & Television Association are all members of Spectrum for the Future. (Disclosure: The Advance/Newhouse Partnership, which owns 12 percent of Charter, is part of Advance Publications, which owns Ars Technica parent Condé Nast.)

When contacted by Ars, a CTIA spokesperson criticized cable companies for “fighting competition” and said the cable firms are being “disingenuous.” Charter and Cox declined to answer our questions about their involvement in Spectrum for the Future. Comcast and the NCTA didn’t respond to requests for comment.

The NCTA and big cable companies are no strangers to lobbying the FCC and Congress and could fight for CBRS entirely on their own. But as it happens, some consumer advocates who regularly oppose the cable industry on other issues are on cable’s side in this battle.

With Spectrum for the Future, the cable industry has allied not just with consumer advocates but also small wireless ISPs and operators of private networks that use spectrum the big mobile companies want for themselves. Another group that is part of the coalition represents schools and libraries that use spectrum to provide local services.

For cable, joining with consumer groups, small ISPs, and others in a broad coalition has an obvious advantage from a public relations standpoint. “This is a lot of different folks who are in it for their own reasons. Sometimes that’s a big advantage because it makes it more authentic,” said Harold Feld, senior VP of consumer advocacy group Public Knowledge, which is part of Spectrum of the Future.

In some cases, a big company will round up nonprofits to which it has donated to make a show of broad public support for one of the company’s regulatory priorities—like a needed merger approval. That’s not what happened here, according to Feld. While cable companies probably provided most of the funding for Spectrum for the Future, the other members are keenly interested in fighting the wireless lobby over spectrum access.

“There’s a difference between cable being a tentpole member and this being cable with a couple of friends on the side,” Feld told Ars. Cable companies “have the most to lose, they have the most initial resources. But all of these other guys who are in here, I’ve been on these calls, they’re pretty active. There are a lot of diverse interests in this, which sometimes makes it easier to lobby, sometimes makes it harder to lobby because you all want to talk about what’s important to you.”

Feld didn’t help write the group’s press release criticizing Pai but said the points made are “all things I agree with.”

The “everybody but Big Mobile” coalition

Public Knowledge and New America’s Open Technology Institute (OTI), another Spectrum for the Future member, are both longtime proponents of shared spectrum. OTI’s Wireless Future Project director, Michael Calabrese, told Ars that Spectrum for the Future is basically the “everybody but Big Mobile” wireless coalition and “a very broad but ad hoc coalition.”

While Public Knowledge and OTI advocate for shared spectrum in many frequency bands, Spectrum for the Future is primarily focused on one: the Citizens Broadband Radio Service (CBRS), which spans from 3550 MHz to 3700 MHz. The CBRS spectrum is used by the Department of Defense and shared with non-federal users.

CBRS users in the cable industry and beyond want to ensure that CBRS remains available to them and free of high-power mobile signals that would crowd out lower-power operations. They were disturbed by AT&T’s October 2024 proposal to move CBRS to the lower part of the 3 GHz band, which is also used by the Department of Defense, and auction existing CBRS frequencies to 5G wireless companies “for licensed, full-power use.”

The NCTA told the FCC in December that “AT&T’s proposal to reallocate the entire 3 GHz band is unwarranted, impracticable, and unworkable and is based on the false assertion that the CBRS band is underutilized.”

Big mobile companies want the CBRS spectrum because it is adjacent to frequencies that are already licensed to them. The Department of Defense seems to support AT&T’s idea, even though it would require moving some military operations and sharing the spectrum with non-federal users.

Pentagon plan similar to AT&T’s

In a May research note provided to Ars, New Street Research Policy Advisor Blair Levin reported some details of a Department of Defense proposal for several bands of spectrum, including CBRS. The White House asked the Department of Defense “to come up with a plan to enable allocation of mid-band exclusive-use spectrum,” and the Pentagon recently started circulating its initial proposal.

The Pentagon plan is apparently similar to AT&T’s, as it would reportedly move current CBRS licensees and users to the lower 3 GHz band to clear spectrum for auctions.

“It represents the first time we can think of where the government would change the license terms of one set of users to benefit a competitor of that first set of users… While the exclusive-use spectrum providers would see this as government exercising its eminent domain rights as it has traditionally done, CBRS users, particularly cable, would see this as the equivalent of a government exercis[ing] its eminent domain rights to condemn and tear down a Costco to give the land to a Walmart,” Levin wrote.

If the proposal is implemented, cable companies would likely sue the government “on the grounds that it violates their property rights” under the priority licenses they purchased to use CBRS, Levin wrote. Levin’s note said he doesn’t think this proposal is likely to be adopted, but it shows that “the game is afoot.”

CBRS is important to cable companies because they have increasingly focused on selling mobile service as another revenue source on top of their traditional TV and broadband businesses. Cable firms got into the mobile business by reselling network access from the likes of Verizon. They’ve been increasing the use of CBRS, reducing their reliance on the major mobile companies, although a recent Light Reading article indicates that cable’s progress with CBRS deployment has been slow.

In its statement to Ars, CTIA said the cable industry “opposes full-power 5G access in the US at every opportunity” in CBRS and other spectrum bands. Cable companies are “fighting competition” from wireless operators “every chance they can,” CTIA said. “With accelerating losses in the marketplace, their advocacy is now more aggressive and disingenuous.”

The DoD plan that reportedly mirrors AT&T’s proposal seems to represent a significant change from the Biden-era Department of Defense’s stance. In September 2023, the department issued a report saying that sharing the 3.1 GHz band with non-federal users would be challenging and potentially cause interference, even if rules were in place to protect DoD operations.

“DoD is concerned about the high possibility that non-Federal users will not adhere to the established coordination conditions at all times; the impacts related to airborne systems, due to their range and speed; and required upgrades to multiple classes of ships,” the 2023 report said. We contacted the Department of Defense and did not receive a response.

Levin quoted Calabrese as saying the new plan “would pull the rug out from under more than 1,000 CBRS operators that have deployed more than 400,000 base stations. While they could, in theory, share DoD spectrum lower in the band, that spectrum will now be so congested it’s unclear how or when that could be implemented.”

Small ISP slams “AT&T and its cabal of telecom giants”

AT&T argues that CBRS spectrum is underutilized and should be repurposed for commercial mobile use because it “resides between two crucial, high-power, licensed 5G bands”—specifically 3.45–3.55 GHz and 3.7–3.98 GHz. It said its proposal would expand the CBRS band’s total size from 150 MHz to 200 MHz by relocating it to 3.1–3.3 GHz.

Keefe John, CEO of a Wisconsin-based wireless home Internet provider called Ethoplex, argued that “AT&T and its cabal of telecom giants” are “scheming to rip this resource from the hands of small operators and hand it over to their 5G empire. This is nothing less than a brazen theft of America’s digital future, and we must fight back with unrelenting resolve.”

John is vice chairperson of the Wireless Internet Service Providers Association (WISPA), which represents small ISPs and is a member of Spectrum for the Future. He wrote that CBRS is a “vital spectrum band that has become the lifeblood of rural connectivity” because small ISPs use it to deliver fixed wireless Internet service to underserved areas.

John called the AT&T proposal “a deliberate scheme to kneecap WISPs, whose equipment, painstakingly deployed, would be rendered obsolete in the lower band.” Instead of moving CBRS from one band to another, John said CBRS should stay on its current spectrum and expand into additional spectrum “to ensure small providers have a fighting chance.”

An AT&T spokesperson told Ars that “CBRS can coexist with incumbents in the lower 3 GHz band, and with such high demand for spectrum, it should. Thinking creatively about how to most efficiently use scarce spectrum to meet crucial needs is simply good public policy.”

AT&T said that an auction “would provide reimbursement for costs associated with” moving CBRS users to other spectrum and that “the Department of Defense has already stated that incumbents in the lower 3 GHz could share with low-power commercial uses.”

“Having a low-power use sandwiched between two high-power use cases is an inefficient use of spectrum that doesn’t make sense. Our proposal would fix that inefficiency,” AT&T said.

AT&T has previously said that under its proposal, CBRS priority license holders “would have the choice of relocating to the new CBRS band, accepting vouchers they can use toward bidding on new high-power licenses, or receiving a cash payment in exchange for the relinquishment of their priority rights.”

Democrat warns of threat to naval operations

Reallocating spectrum could require the Navy to move from the current CBRS band to the lower part of 3 GHz. US Senator Maria Cantwell (D-Wash.) sent a letter urging the Department of Defense to avoid major changes, saying the current sharing arrangement “allows the Navy to continue using high-power surveillance and targeting radars to protect vessels and our coasts, while also enabling commercial use of the band when and where the Navy does not need access.”

Moving CBRS users would “disrupt critical naval operations and homeland defense” and “undermine an innovative ecosystem of commercial wireless technology that will be extremely valuable for robotic manufacturing, precision agriculture, ubiquitous connectivity in large indoor spaces, and private wireless networks,” Cantwell wrote.

Cantwell said she is also concerned that “a substantial number of military radar systems that operate in the lower 3 GHz band” will be endangered by moving CBRS. She pointed out that the DoD’s September 2023 report said the 3.1 GHz range has “unique spectrum characteristics” that “provide long detection ranges, tracking accuracy, and discrimination capability required for DoD radar systems.” The spectrum “is low enough in the frequency range to maintain a high-power aperture capability in a transportable system” and “high enough in the frequency range that a sufficient angular accuracy can be maintained for a radar track function for a fire control capability,” the DoD report said.

Spectrum for the Future members

In addition to joining the cable industry in Spectrum for the Future, public interest groups are fighting for CBRS on their own. Public Knowledge and OTI teamed up with the American Library Association, the Benton Institute for Broadband & Society, the Schools Health & Libraries Broadband (SHLB) Coalition, and others in a November 2024 FCC filing that praised the pro-consumer virtues of CBRS.

“CBRS has been the most successful innovation in wireless technology in the last decade,” the groups said. They accused the big three mobile carriers of “seeking to cripple CBRS as a band that promotes not only innovation, but also competition.”

These advocacy groups are interested in helping cable companies and small home Internet providers compete against the big three mobile carriers because that opens new options for consumers. But the groups also point to many other use cases for CBRS, writing:

CBRS has encouraged the deployment of “open networks” designed to host users needing greater flexibility and control than that offered by traditional CMRS [Commercial Mobile Radio Services] providers, at higher power and with greater interference protection than possible using unlicensed spectrum. Manufacturing campuses (such as John Deere and Dow Chemical), transit hubs (Miami International Airport, Port of Los Angeles), supply chain and logistic centers (US Marine Corps), sporting arenas (Philadelphia’s Wells Fargo Center), school districts and libraries (Fresno Unified School District, New York Public Library) are all examples of a growing trend toward local spectrum access fueling purpose-built private LTE/5G networks for a wide variety of use cases.

The SHLB told Ars that “CBRS spectrum plays a critical role in helping anchor institutions like schools and libraries connect their communities, especially in rural and underserved areas where traditional broadband options may be limited. A number of our members rely on access to shared and unlicensed spectrum to deliver remote learning and essential digital services, often at low or no cost to the user.”

Spectrum for the Future’s members also include companies that sell services to help customers deploy CBRS networks, as well as entities like Miami International Airport that deploy their own CBRS-based private cellular networks. The NCTA featured Miami International Airport’s private network in a recent press release, saying that CBRS helped the airport “deliver more reliable connectivity for visitors while also powering a robust Internet of Things network to keep the airport running smoothly.”

Spectrum for the Future doesn’t list any staff on its website. Media requests are routed to a third-party public relations firm. An employee of the public relations firm declined to answer our questions about how Spectrum for the Future is structured and operated but said it is “a member-driven coalition with a wide range of active supporters and contributors, including innovators, anchor institutions, and technology companies.”

Spectrum for the Future appears to be organized by Salt Point Strategies, a public affairs consulting firm. Salt Point Spectrum Policy Analyst David Wright is described as Spectrum for the Future’s policy director in an FCC filing. We reached out to Wright and didn’t receive a response.

One Big Beautiful Bill is a battleground

The Trump-backed “One Big Beautiful Bill,” approved by the House, is one area of interest for both sides of the CBRS debate. The bill would restore the FCC’s expired authority to auction spectrum and require new auctions. One question is whether the bill will simply require the FCC to auction a minimum amount of spectrum or if it will require specific bands to be auctioned.

WISPA provided us with a statement about the version that passed the House, saying the group is glad it “excludes the 5.9 GHz and 6 GHz bands from its call to auction off 600 megahertz of spectrum” but worried because the bill “does not exclude the widely used and previously auctioned Citizens Broadband Radio Service (CBRS) band from competitive bidding, leaving it vulnerable to sale and/or major disruption.”

WISPA said that “spectrum auctions are typically designed to favor large players” and “cut out small and rural providers who operate on the front lines of the digital divide.” WISPA said that over 60 percent of its members “use CBRS to deliver high-quality broadband to hard-to-serve and previously unserved Americans.”

On June 5, Sen. Ted Cruz (R-Texas) released the text of the Senate Commerce Committee proposal, which also does not exclude the 3550–3700 MHz from potential auctions. Pai and AT&T issued statements praising Cruz’s bill.

Pai said that Cruz’s “bold approach answers President Trump’s call to keep all options on the table and provides the President with full flexibility to identify the right bands to meet surging consumer demand, safeguard our economic competitiveness, and protect national security.” AT&T said that “by renewing the FCC’s auction authority and creating a pipeline of mid-band spectrum, the Senate is taking a strong step toward meeting consumers’ insatiable demand for mobile data.”

The NCTA said it welcomed the plan to restore the FCC’s auction authority but urged lawmakers to “reject the predictable calls from large mobile carriers that seek to cripple competition and new services being offered over existing Wi-Fi and CBRS bands.”

Licensed, unlicensed, and in-between

Spectrum is generally made available on a licensed or unlicensed basis. Wireless carriers pay big bucks for licenses that grant them exclusive use of spectrum bands on which they deploy nationwide cellular networks. Unlicensed spectrum—like the bands used in Wi-Fi—can be used by anyone without a license as long as they follow rules that prevent interference with other users and services.

The FCC issued rules for the CBRS band in 2015 during the Obama administration, using a somewhat different kind of system. The FCC rules allow “for dynamic spectrum sharing in the 3.5 GHz band between the Department of Defense (DoD) and commercial spectrum users,” the National Telecommunications and Information Administration notes. “DoD users have protected, prioritized use of the spectrum. When the government isn’t using the airwaves, companies and the public can gain access through a tiered framework.”

Instead of a binary licensed-versus-unlicensed system, the FCC implemented a three-tiered system of access. Tier 1 is for incumbent users of the band, including federal users and fixed satellite service. Tier 1 users receive protection against harmful interference from Tier 2 and Tier 3 users.

Tier 2 of CBRS consists of Priority Access Licenses (PALs) that are distributed on a county-by-county basis through competitive bidding. Tier 2 users get interference protection from users of Tier 3, which is made available in a manner similar to unlicensed spectrum.

Tier 3 “is licensed-by-rule to permit open, flexible access to the band for the widest possible group of potential users,” the FCC says. Tier 3 users can operate throughout the 3550–3700 MHz band but “must not cause harmful interference to Incumbent Access users or Priority Access Licensees and must accept interference from these users. GAA users also have no expectation of interference protection from other GAA users.”

The public interest groups’ November 2024 filing with the FCC said the unique approach to spectrum sharing “allow[s] all would-be users to operate where doing so does not threaten harmful interference” and provides a happy medium between high-powered operations in exclusively licensed spectrum bands and low-powered operations in unlicensed spectrum.

CTIA wants the ability to send higher-power signals in the band, arguing that full-power wireless transmissions would help the US match the efforts of other countries “where this spectrum has been identified as central to 5G.” The public interest groups urged the FCC to reject the mobile industry proposal to increase power levels, saying it “would disrupt and diminish the expanding diversity of GAA users and use cases that represent the central purpose of CBRS’s innovative three-tier, low-power and coordinated sharing framework.”

Pai helped carriers as FCC chair

The FCC’s original plan for PALs during the Obama administration was to auction them off for individual Census tracts, small areas containing between 1,200 and 8,000 people each. During President Trump’s first term, the Pai FCC granted a CTIA request to boost the size of license areas from census tracts to counties, making it harder for small companies to win at auction.

The FCC auctioned PALs in 2020, getting bids of nearly $4.6 billion from 228 bidders. The biggest winners were Verizon, Dish Network, Charter, Comcast, and Cox.

Although Verizon uses CBRS for parts of its network, that doesn’t mean it’s on the same side as cable users in the policy debate. Verizon urged the FCC to increase the allowed power levels in the band. Dish owner EchoStar also asked for power increases. Cable companies oppose raising the power levels, with the NCTA saying that doing so would “jeopardize the continued availability of the 3.5 GHz band for lower-power operations” and harm both federal and non-federal users.

As head of CTIA, one of Pai’s main jobs is to obtain more licensed spectrum for the exclusive use of AT&T, Verizon, T-Mobile, and other mobile companies that his group represents. Pai’s Wall Street Journal op-ed said that “traffic on wireless networks is expected to triple by 2029,” driven by “AI, 5G home broadband and other emerging technologies.” Pai cited a study commissioned by CTIA to argue that “wireless networks will be unable to meet a quarter of peak demand in as little as two years.”

Spectrum for the Future countered that Pai “omits that the overwhelming share of this traffic will travel over Wi-Fi, not cellular networks.” CTIA told Ars that “the Ericsson studies we use for traffic growth projections only consider demand over commercial networks using licensed spectrum.”

Spectrum for the Future pointed to statements made by the CEOs of wireless carriers that seem to contradict Pai’s warnings of a spectrum shortage:

Mr. Pai cites a CTIA-funded study to claim “wireless networks will be unable to meet a quarter of peak demand in as little as two years.” If that’s true, then why are his biggest members’ CEOs telling Wall Street the exact opposite?

Verizon’s CEO insists he’s sitting on “a generation of spectrum”—”years and years and years” of spectrum capacity still to deploy. The CEO of Verizon’s consumer group goes even further, insisting they have “almost unlimited spectrum.” T-Mobile agrees, bragging that it has “only deployed 60 percent of our mid-band spectrum on 5G,” leaving “lots of spectrum we haven’t put into the fight yet.”

Battle could last for years

Spectrum for the Future also scoffed at Pai’s comparison of the US to China. Pai’s op-ed said that China “has accelerated its efforts to dominate in wireless and will soon boast more than four times the amount of commercial midband spectrum than the US.” Pai added that “China isn’t only deploying 5G domestically. It’s exporting its spectrum policies, its equipment vendors (such as Huawei and ZTE), and its Communist Party-centric vision of innovation to the rest of the world.”

Spectrum for the Future responded that “China’s spectrum policy goes all-in on exclusive-license frameworks, such as 5G, because they limit spectrum access to just a small handful of regime-aligned telecom companies complicit in Beijing’s censorship regime… America’s global wireless leadership, by contrast, is fueled by spectrum innovations like unlicensed Wi-Fi and CBRS spectrum sharing, whose hardware markets are dominated by American and allied companies.”

Spectrum for the Future also said that Pai and CTIA “blasting China for ‘exporting its spectrum policies’—while asking the US to adopt the same approach—is stunning hypocrisy.”

CTIA’s statement to Ars disputed Spectrum for the Future’s description. “The system of auctioning spectrum licenses was pioneered in America but is not used in China. China does, however, allocate unlicensed spectrum in a similar manner to the United States,” CTIA told Ars.

The lobbying battle and potential legal war that has Pai and CTIA lined up against the “everybody but Big Mobile” wireless coalition could last throughout Trump’s second term. Levin’s research note about the DoD proposal said, “the path from adoption to auction to making the spectrum available to the winners of an auction is likely to be at least three years.” The fight could go on a lot longer if “current licensees object and litigate,” Levin wrote.

cybercriminals-turn-to-“residential-proxy”-services-to-hide-malicious-traffic

Cybercriminals turn to “residential proxy” services to hide malicious traffic

For years, gray market services known as “bulletproof” hosts have been a key tool for cybercriminals looking to anonymously maintain web infrastructure with no questions asked. But as global law enforcement scrambles to crack down on digital threats, they have developed strategies for getting customer information from these hosts and have increasingly targeted the people behind the services with indictments. At the cybercrime-focused conference Sleuthcon in in Arlington, Virginia on Friday, researcher Thibault Seret outlined how this shift has pushed both bulletproof hosting companies and criminal customers toward an alternative approach.

Rather than relying on web hosts to find ways of operating outside law enforcement’s reach, some service providers have turned to offering purpose-built VPNs and other proxy services as a way of rotating and masking customer IP addresses and offering infrastructure that either intentionally doesn’t log traffic or mixes traffic from many sources together. And while the technology isn’t new, Seret and other researchers emphasized to WIRED that the transition to using proxies among cybercrminals over the last couple of years is significant.

“The issue is, you cannot technically distinguish which traffic in a node is bad and which traffic is good,” Seret, a researcher at the threat intelligence firm Team Cymru, told WIRED ahead of his talk. “That’s the magic of a proxy service—you cannot tell who’s who. It’s good in terms of internet freedom, but it’s super, super tough to analyze what’s happening and identify bad activity.”

The core challenge of addressing cybercriminal activity hidden by proxies is that the services may also, even primarily, be facilitating legitimate, benign traffic. Criminals and companies that don’t want to lose them as clients have particularly been leaning on what are known as “residential proxies,” or an array of decentralized nodes that can run on consumer devices—even old Android phones or low end laptops—offering real, rotating IP addresses assigned to homes and offices. Such services offer anonymity and privacy, but can also shield malicious traffic.

anti-vaccine-quack-hired-by-rfk-jr.-has-started-work-at-the-health-department

Anti-vaccine quack hired by RFK Jr. has started work at the health department

Outside researchers can request access to VSD data by submitting study proposals to the CDC. The Geiers have, in the past, gained access. But, they lost that access at least twice, the Journal reported. In 2004, the CDC kicked the Geiers out after officials determined that they had misrepresented their plans for the data when they initially submitted their proposal to the CDC. They were barred again in 2006.

Now an HHS employee, Geier is seeking access to the data once again. The Journal reports that Kennedy has assigned researchers at the National Institutes of Health to assist Geier and that those NIH employees have sent a request to the CDC to hand over all of VSD’s data. This request reportedly caused alarm at the CDC and the project’s health care sites around the country, which are concerned about protecting the security of private patient data.

It’s unclear whether Geier has regained access to the data. But people familiar with the matter told the Journal that Geier aims to reanalyze the CDC’s data on thimerosal to try to prove a link to autism. The sources also said that Geier is interested in proving that the CDC is corrupt.

In the May hearing, Kennedy, who also supports the debunked claim that vaccines cause autism, defended Geier. Kennedy said that “there has been a lot of monkey business with the VSD” and that Geier is “the only living independent scientist” who has seen the data and can determine if it has been altered. (Hassan interjected that Geier is not a scientist.) Kennedy also falsely claimed that a court overturned the medical board’s finding that he had practiced medicine without a license and awarded Geier $5 million.

That did not happen. But Kennedy may have been referring to the fact that Mark Geier filed a lawsuit against the medical board over a 2012 cease-and-desist order that alleged he improperly prescribed medication for himself, his wife, and his son while his medical license was suspended. Mark Geier sued the board, saying the order was malicious because it contained personal information, including the medications Geier had prescribed. A Circuit Court sided with the Geiers, awarding them nearly $5 million in total. But the win and the award were overturned on appeal in 2019.
