Trump administration bans Anthropic from federal use over AI safety dispute

President Donald Trump announced that all federal government agencies must cease using Anthropic's AI tools. Defense Secretary Pete Hegseth declared that the company would be deemed a supply chain risk. The actions resulted from Anthropic refusing to back down in its negotiations with the Pentagon over requested restrictions on its AI system being used in autonomous weapons and mass surveillance of US citizens. Anthropic said it plans to legally challenge the supply chain risk designation. The designation is normally reserved for companies with direct connections to foreign adversaries. It would require all contractors who work with the military to prove their military work does not touch Anthropic's products. Anthropic had requested prohibitions on domestic mass surveillance and requirements for human responsibility in the use of force, including autonomous weapon systems. It is not clear what is different about its requested terms. CNN has asked the Pentagon for clarifications.
