A federal judge has granted temporary relief to the U.S. government in relation to Anthropic's case against the Pentagon, ruling that it violated its First Amendment right to free speech and Fifth Amendment rights to due process. The company had filed a lawsuit alleging that Defense Secretary Pete Hegseth exceeded his authority by labeling Anthropic as a national security supply-chain risk, usually used for companies that could expose military systems to hacking or sabotage. The dispute began after Anthropic refused to allow the military use its AI chatbot, Claude, for surveillance or weapons due to concerns about AI safety and could cost billions of dollars and damage its reputation. Anthropic is also fighting a second case in Washington, D.C., over a similar designation that could prevent it from receiving civilian government contracts.
