Judge temporarily blocks enforcement of Anthropic supply chain risk designation

Mar 26, 2026

U.S. District Judge Rita Lin issued a 43-page ruling Thursday temporarily blocking the Pentagon's supply chain risk designation against Anthropic, finding the government's own records showed the action was likely unconstitutional retaliation for the AI company's public criticism. The dispute arose after Anthropic, whose Claude AI model was the only one deployed on military classified systems and used in the war with Iran, pushed to bar the military from using Claude for domestic surveillance and fully autonomous weapons. After talks broke down last month, Defense Secretary Pete Hegseth labeled Anthropic a supply chain risk and President Trump ordered all federal agencies to immediately cease using the company's technology, calling it a radical left, woke company. Judge Lin found the government hadn't shown why Anthropic posed a supply chain risk or followed required legal processes, calling the measures Orwellian and stating that punishing a company for bringing public scrutiny to government contracting positions constitutes classic illegal First Amendment retaliation.
