Anthropic Files Sworn Declarations Challenging Pentagon's Supply Chain Risk Claims Ahead of Injunction Hearing

Anthropic filed sworn declarations in California federal court disputing the Pentagon's assertion that the company poses a national security risk, ahead of a Tuesday preliminary injunction hearing before District Judge Rita Lin. The company's policy and public sector leaders contested Pentagon claims around control and security risks, argued that key government concerns were never raised during negotiations, emphasized Anthropic never sought operational oversight of military use, and maintained its deployed systems cannot be remotely altered or accessed. Senator Warren separately sent a letter to Hegseth characterizing the supply-chain risk designation as 'retaliation,' arguing the Pentagon could have simply terminated Anthropic's $200 million contract. Multiple tech firms including OpenAI, Google, and Microsoft filed amicus briefs supporting Anthropic.
