Anthropic's Tom Brown Leads White House Talks as Trump Tone Shifts

The Trump administration's posture toward Anthropic shifted noticeably in the days after co-founder and Chief Compute Officer Tom Brown stepped in to lead the company's Washington engagement, according to Wired. Brown arrived at the Commerce Department on June 15 alongside policy head Sarah Heck to begin emergency talks over the June 12 export-control directive that had forced Fable 5 and Mythos 5 offline — just three days after their public launch. By June 19, President Trump was saying Anthropic was no longer a national-security threat and praising the company for "behaving very responsibly."

The underlying dispute centers on a contested jailbreak claim. Commerce Secretary Howard Lutnick's directive, issued under the Export Control Reform Act of 2018, cited the risk that the models could be used by "military intelligence users in China, Russia, or other countries of concern." Amazon researchers had reportedly bypassed Fable 5's safety filters, and separately, Mythos had reportedly identified vulnerabilities in NSA classified systems within hours. Anthropic pushed back, stating it had "not even received a disclosure of a concerning non-universal potential jailbreak that led to a harmful result."

The decision to send Brown — a co-founder who runs the company's compute operations — rather than only government-affairs staff was read by observers as a signal that Anthropic was treating the standoff as a technical disagreement to be worked through, not a policy fight to be managed. Dario Amodei did attend the G7 summit on June 17, where he met Trump face to face and reportedly proposed international cooperation on AI with the United States taking the lead.

What the reporting does not give you is a clear picture of what a deal would actually look like — whether it involves model modifications, usage restrictions, or some monitoring arrangement. Prediction markets on Kalshi put the odds of restoration before July 1 at roughly 57%, with Polymarket considerably lower at 34 to 41 percent. Four members of Congress sent Commerce Secretary Lutnick a formal letter on June 18 demanding a written explanation by June 26, adding a political clock to talks that, as of the Wired reporting, had not produced an announced agreement.
