DOJ Defends Anthropic War-AI Restrictions, Court Battle Over Pentagon Access Persists

The U.S. Department of Justice told a federal court that Anthropic’s designation as a supply-chain risk and restrictions on Claude AI for Pentagon use are lawful, arguing the government did not violate Anthropic’s First Amendment rights and that security concerns justify limiting access to DoD systems. Anthropic contends the government overstepped its authority and seeks relief in a lawsuit that could cost the company billions in revenue; a hearing is scheduled as the Defense Department weighs replacing Anthropic’s tools with offerings from Google, OpenAI, and xAI while the case unfolds.
