Anthropic Banned from U.S. Federal Use After DOJ Refuses Unrestricted AI for Military Surveillance
In early 2026, the Trump administration ordered all federal agencies to cease using Anthropic's Claude AI models and designated the company a "Supply-Chain Risk to National Security" under the Federal Acquisition Supply Chain Security Act. The conflict originated when the Department of Defense demanded unrestricted access to Claude for "all lawful purposes," including potential use in autonomous weapons and domestic surveillance. Anthropic refused, citing civil liberties and human rights concerns. On February 27, President Trump issued an immediate cease directive with a six-month phase-out period. By March 5, the DOD's supply-chain designation took effect, barring military contractors from any commercial activity with Anthropic and removing the company from federal procurement systems.
