Anthropic submitted two sworn declarations to a California federal court docket late Friday afternoon, pushing again on the Pentagon’s assertion that the AI firm poses an “unacceptable threat to nationwide safety” and arguing that the federal government’s case depends on technical misunderstandings and claims that had been by no means really raised through the months of negotiations that preceded the dispute.
The declarations had been filed alongside Anthropic’s reply transient in its lawsuit towards the Division of Protection and are available forward of a listening to this coming Tuesday, March 24, earlier than Decide Rita Lin in San Francisco.
The dispute traces again to late February, when President Trump and Protection Secretary Pete Hegseth publicly declared they had been reducing ties with Anthropic after the corporate refused to permit unrestricted army use of its AI know-how.
The 2 individuals who submitted the declarations are Sarah Heck, Anthropic’s Head of Coverage, and Thiyagu Ramasamy, the corporate’s Head of Public Sector.
Heck is a former Nationwide Safety Council official who labored on the White Home beneath the Obama administration earlier than shifting to Stripe after which Anthropic, the place she runs the corporate’s authorities relationships and coverage work. She was personally current on the February 24 assembly the place CEO Dario Amodei sat down with Protection Secretary Hegseth and the Pentagon’s Underneath Secretary Emil Michael.
In her declaration, Heck calls out what she describes as a central falsehood within the authorities’s filings: that Anthropic demanded some type of approval function over army operations. That declare, she says, merely isn’t true. “At no time throughout Anthropic’s negotiations with the Division did I or another Anthropic worker state that the corporate wished that type of function,” she wrote.
She additionally claims that the Pentagon’s concern about Anthropic doubtlessly disabling or altering its know-how mid-operation was by no means raised throughout negotiations. As an alternative, she says, it appeared for the primary time within the authorities’s court docket filings, which gave Anthropic no alternative to reply.

One other element in Heck’s declaration positive to attract consideration is that on March 4 — the day after the Pentagon formally finalized its supply-chain threat designation towards Anthropic — Underneath Secretary Michael emailed Amodei to say the 2 sides had been “very shut” on the 2 points the federal government now cites as proof that Anthropic is a nationwide safety risk: its positions on autonomous weapons and mass surveillance of People.
The e-mail, which Heck attaches as an exhibit to her declaration, is price studying alongside what Michael stated publicly within the days afterward. On March 5, Amodei revealed a press release saying the corporate had been having “productive conversations” with the Pentagon. The day after that, Michael posted on X that “there isn’t any energetic Division of Struggle negotiation with Anthropic.” Every week after that, he advised CNBC there was “no likelihood” of renewed talks.
Heck’s level seems to be: If Anthropic’s stance on these two points is what makes it a nationwide safety risk, why was the Pentagon’s personal official saying the 2 sides had been practically aligned on precisely these points proper after the designation was finalized? (She stops in need of saying the federal government used the designation as a bargaining chip, however the timeline she lays out leaves the query hanging.)
Ramasamy brings a distinct type of experience to the case. Earlier than becoming a member of Anthropic in 2025, he spent six years at Amazon Net Providers managing AI deployments for presidency clients, together with labeled environments. At Anthropic, he’s credited with constructing the staff that introduced its Claude fashions into nationwide safety and protection settings, together with the $200 million contract with the Pentagon introduced final summer time.
His declaration takes on the federal government’s declare that Anthropic may theoretically intrude with army operations by disabling the know-how or in any other case altering the way it behaves, which Ramasamy says isn’t technically potential. Per his telling, as soon as Claude is deployed inside a government-secured, “air-gapped” system operated by a third-party contractor, Anthropic has no entry to it; there isn’t any distant kill change, no backdoor, and no mechanism to push unauthorized updates. Any type of “operational veto” is a fiction, he suggests, explaining {that a} change to the mannequin would require the Pentagon’s express approval and motion to put in.
Anthropic, he says, can’t even see what authorities customers are typing into the system, not to mention extract that knowledge.
Ramasamy additionally disputes the federal government’s declare that Anthropic’s hiring of overseas nationals makes the corporate a safety threat. He notes that Anthropic workers have undergone U.S. authorities safety clearance vetting — the identical background verify course of required for entry to labeled data — including in his declaration that “to my information,” Anthropic is the one AI firm the place cleared personnel really constructed the AI fashions designed to run in labeled environments.
Anthropic’s lawsuit argues that the supply-chain threat designation — the primary ever utilized to an American firm — quantities to authorities retaliation for the corporate’s publicly said views on AI security, in violation of the First Modification.
The federal government, in a 40-page submitting earlier this week, rejected that framing entirely, saying that Anthropic’s refusal to permit all lawful army makes use of of its know-how was a enterprise determination, not protected speech, and that the designation was an easy nationwide safety name and never punishment for the corporate’s views.
