Federal judge temporarily blocks Pentagon's supply chain risk designation of AI company Anthropic

U.S. District Judge Rita Lin granted a preliminary injunction on Thursday blocking the Pentagon's designation of AI company Anthropic as a supply chain risk and President Trump's order for federal agencies to stop using the company's Claude chatbot. The judge ruled the actions appeared to be First Amendment retaliation against Anthropic for publicly criticizing the government's contracting position. The dispute arose from failed contract negotiations where Anthropic sought to prevent its AI technology from being used for mass surveillance of Americans and fully autonomous weapons.
