# U.S. Judge Blocks Trump Defense Department’s Anthropic Blacklisting > Source: > Published: 2026-08-28 02:59:46+00:00 Jack Queen, Reuters: A U.S. judge on Thursday blocked the Pentagon’s blacklisting of Anthropic, the latest turn in the Claude maker’s high-stakes fight with the military over AI safety on the battlefield. Anthropic’s lawsuit in California federal court alleges that Defense Secretary Pete Hegseth overstepped his authority when he designated Anthropic a national security supply-chain risk, a label the government can apply to companies that expose military systems to potential infiltration or sabotage by adversaries. [...] U.S. District Judge Rita Lin, an appointee of former Democratic President Joe Biden, made the ruling in a 59-page order where she found that the Pentagon’s decision was “illegal and baseless.” “The empty invocation of national security is not a blank check to punish and retaliate against government critics,” she wrote. The imperial aspects of Trump 2.0 are increasingly coming apart at the seams.
