The encrypted messaging app Signal has become a critical tool for organizers following the actions of immigration agents in Minneapolis. Now that activity is the target of a probe launched personally by FBI Director Kash Patel — one that has Constitutional law experts questioning its merits.
Criticism of the Signal investigation was swift from figures on both the right and left. The libertarian Cato Institute called the investigation an “epic constitutional and legal fail by Patel.”
Whether or not courts would accept any action bought by Patel against Signal or its users, the circumstances are at least highly unusual: Patel announced the probe via podcast.
Patel discussed the investigation during Monday’s episode of The Benny Show, a podcast hosted by the right-wing commentator Benny Johnson. Patel alleged, without evidence, that participants in the chat might have incited violence, threatened law enforcement, or broke the law.

Patel said that alleged screenshots from a Signal chat amongst Minneapolis anti-ICE organizers posted to X by the rightwing, self-described independent journalist Cam Higby led to the investigation.
Higby has said he hopes the government conducts a “witch hunt” of the Signal chat participants, who were allegedly sharing information about license plates belonging to cars driven by federal immigration officers.
“We immediately opened up that investigation because that sort of Signal chat being coordinated with individuals, not just locally in Minnesota, but maybe even around the country,” Patel said. “If that leads to a break in the federal statute or a violation of some law, then we are going to arrest people.”
Signal did not respond to Mashable’s request for comment on the investigation. The X accounts belonging to the app and its president, Meredith Whittaker, have remained silent on the investigation.
Here’s what you need to know about whether the investigation has merit and how it unfolded:
Does the FBI Signal chat investigation violate Constitutional rights?
Patel insisted that the investigation wouldn’t infringe on the public’s First Amendment right to express political speech and protest but rather focus on illegal activity.
Yet legal and Constitutional scholars have questioned whether the Signal chat participants were doing anything illegal.

In an interview with the Guardian, First Amendment expert Kevin Goldberg said that his review of Higby’s social media posts revealed nothing clearly illegal.
“I got the sense the [Signal chat] group has been organized for purposes that are fully protected by the First Amendment: To observe, to speak, and to alert others of possible dangers,” said Goldberg, vice president of the Freedom Forum, a nonpartisan foundation that works on First Amendment issues. “I didn’t see anything that impedes or obstructs justice. The claimed ‘doxing’ of law enforcement is not necessary illegal.”
Patrick G. Eddington, senior fellow at the Cato Institute, had a cutting response for the Trump administration and Patel.
“I suppose it was just a matter of time before a Trump administration official would suggest that the use of public key encryption — protected by the First Amendment — to monitor federal agent misconduct was itself allegedly a crime,” he wrote in an article on the Cato Institute’s website. “This is another epic constitutional and legal fail by Patel.”
Eddington added that a decades-old federal court case affirmed citizens’ First Amendment right to coordinate peaceful protest activity, and even monitor an agency like ICE for “acts of brutality,” using encrypted speech.
On Thursday, Higby alleged on X that he had more material to leak about the Signal chat he infiltrated.
How did the FBI learn about the Signal chat?
When Patel spoke on Johnson’s show, he followed an interview with Higby, who alleged on X that he attempted and succeeded in infiltrating the anti-ICE organizers’ group Signal chat.
Higby admitted to Johnson that though he isn’t a “legal expert,” he viewed the Signal exchanges as a “mass conspiracy” to violate federal law because the participants were, in his opinion, “engaging in collusion against federal law enforcement.”
When Johnson asked Higby how he wanted the FBI to respond, Higby made his goal clear. “I want to see a witch hunt January 6th style,” Higby said, referencing the federal prosecution of insurrectionists who stormed the U.S. Capitol in 2021.
Patel was literally the next guest on Johnson’s show. He said Higby’s X post on his alleged infiltration of the Signal chat triggered his decision.
“As soon as Higby put that [X social media] post out, I opened an investigation on it,” Patel said. He argued that the practice aligns with the FBI’s policy of following publicly-provided tips, leads, and information.
Speaking with Fox News’ Sean Hannity, Patel indicated that the FBI would issue subpoenas, collect data, call grand juries, and “find out who broke the law.”
What to know about using Signal
Though Signal uses end-to-end encryption, that doesn’t mean user messages will be protected from the government.
Signal’s website acknowledges it will disclose transcripts of chats when legally compelled by the government or law enforcement agencies.
ICE reportedly also has a contract with the digital forensics company Cellebrite to help officials unlock phones to retrieve all of their data, including apps, location history, and Signal messages, according to the Electronic Frontier Foundation.

What every U.K. AI startup wants to know these days is, how can I get office space in King’s Cross?
The area is so hot that a VC firm allegedly recently won a deal by promising a founder office space in the neighborhood. “We stop at nothing to win deals [for] and to support” founders, “including helping them source office space when needed,” the firm told me when asked about the rumor, declining to confirm or deny any details.
The neighborhood’s popularity began back in 2016 when DeepMind — then newly acquired by Google — moved in. Soon after, a flood of AI startups followed, wanting to be around the Google DeepMind magic. Today, they hope to take advantage of the cluster of AI talent there.
This has transformed King’s Cross into one of the world’s top AI hubs, rivaled only by San Francisco and Beijing. Around London, it’s known by the sobriquet “Knowledge Quarter,” as it’s home to names like OpenAI, Meta, Isomorphic Labs, Cusp AI, Wayne, Recursive, and, a little farther down the road, Synthesia and Anthropic. The European Technology Network (ETN) just moved into a glossy new office nearby, while University College London sits around the corner.
Mixed in with the new developments are trendy food spots like Hoppers and BAO. Hop a train from King’s Cross, and founders can be in Cambridge in 45 minutes to source talent or can be in Paris in two hours to strike a deal.
Who would have guessed that a little more than 20 years ago, this was one of the seediest areas in London?
“In the ’80s, crack and heroin made the area a major narcotics market,” Hussein Kanji, an investor at Hoxton Ventures, said, recalling syringes in tree trunks and gangs patrolling the streets. “In 1982, the local church was occupied by the English Collective of Prostitutes for 12 straight days.” Then, in the early 2000s, a real estate developer had a dream and, well, “now it is the AI hotbed of the United Kingdom,” Kanji said. “What a change.” Around 18 months ago, his portfolio company BioCorteX moved from the neighborhood Holborn to the Jellicoe building in King’s Cross, hoping to be near the action. “Lots going on in London right now,” Nik Sharma, co-founder of BioCorteX, told me. “Lots of hyperscalers moving in.” That includes, reportedly, Jeff Bezos’ AI company Prometheus, which is also said to be in talks to move into the Jellicoe.
There are around 3,600 AI startups in London, which, together, have raised around .1 billion out of the .8 billion raised in the city since late July, according to Dealroom. Since the start of June, AI-related startups have leased more than 1 million square feet of office space in London, according to the real estate firm Knight Frank. With that, prime rents in King’s Cross have risen 18% over the past three years, Chris Dunn, a commercial insight associate at the firm, told me. That percentage represents only the largest leases encompassing at least 10,000 square feet, like the ones OpenAI and Prometheus are signing. The shorter deals go for even more, he said, and now the vacancy rate for conventional office space is just 0.9%. “Demand has outstripped supply,” he continued.
Today, one of the big topics of the area is sovereignty. It was a wake-up call for many when Anthropic shut off access to Mythos and Fable this summer, leaving some in the ecosystem to conclude: “We’d better look after ourselves,” Saul Klein, co-founder of the VC firm Phoenix Court, told me.
Phoenix Court is located in the King’s Cross area and has three portfolio companies in the vicinity, including Olix (which just announced a .3 billion valuation), Early Health and CoMind. Robin Klein, co-founder of the firm, said the shutdown of Fable and Mythos access was a “small but sharp reminder that Europe can’t simply rent its AI capabilities and capacity; it needs to build and hold some of its own.” King’s Cross, he said, is where much of this building is actually happening.
“The bigger question,” he continued, “is whether the U.K. builds the infrastructure, compute, energy, capital, to make this self-reliance durable, rather than just hosting outposts of U.S. labs.”

Top founders want to stay
Simon Kohl, founder of Latent Labs, has offices in King’s Cross and San Francisco. The London office, at the moment, is growing faster, and he’s more bullish than ever on the ecosystem, he said. “The mood right now feels less like London trying to catch up and more like London becoming one of the default places to start a serious AI company,” he said. Look around and you are likely to see Wayve testing its autonomous cars. Founded in 2017 by co-founder Alex Kendall, the unicorn is one of London’s biggest success stories.
“Ten years ago, building a frontier AI company from London felt like an unusual choice,” Kendall told me. “Now it feels like an obvious one.” Wayve moved into King’s Cross in 2018 looking for a space that could double as a garage — “a rare combination in Central London,” Kendall said. He has watched the ecosystem mature around him — and it’s now evident that a startup can stay in London, raise serious capital, hire world-class AI talent, and remain globally competitive, he said. Down the street from Anthropic’s new 158,000-square-foot office is the AI agent builder Sierra and the AI video platform Synthesia.
Laura Gonzalez Florez, Synthesia’s chief of staff and head of people, says the company moved into its glossy new office building a year ago to accommodate its growing team. They were drawn to the area for the same reason as everyone else: “It’s very close to the airport … very close to where a lot of investors are,” she said.

Around two-thirds of Synthesia’s engineers are remote, Gonzalez Florez said, letting the company tap into an affordable, international, and diverse talent pool and helping it scale faster. “From London, we can hire and work, without any problem, people from anywhere, from Slovenia to Portugal,” she said.
Unsurprisingly, London’s AI boom is also causing a talent war.U.K. AI job postings have skyrocketed in the past few years, per data from PwC. When Anthropic announced it moved into town earlier this year, it listed, for example, a salary range of £260,000 to £630,000 for a machine learning research engineer when the average salary in London for the same role is around £102,000. Some founders in the U.K., like those in Silicon Valley, are being forced to raise more and bigger rounds to keep up.
“The real test is whether more globally significant AI companies are founded, funded, and scaled from the U.K., while continuing to attract the world’s best talent to build them here,” Zain Ali, founder of the King’s Cross-based AI legal firm Centuro, told me. “If that continues to happen, King’s Cross won’t just be an AI hub. It’ll become one of the U.K.’s most important strategic assets.”
