US President Donald Trump has directed every federal agency to immediately stop using technology from AI developer Anthropic, stating in a Truth Social post that "they do not need it and will not do business with them again." Trump made the comments just before a deadline the Pentagon had given Anthropic to grant it unfettered access to the firm’s AI tools. Anthropic’s boss, Dario Amodei, said earlier this week that he would not bend to such demands over concerns that Anthropic would be used in mass surveillance and fully autonomous weapons, adding that if the US Department of Defense chose to stop using the company’s tools, the company would work to enable a smooth transition to another provider. As the Pentagon’s deadline approached, Trump released a barrage of messages on Truth Social, saying Anthropic "better get their act together and be helpful during this phase-out period, or he will use the Full Power of the Presidency to make them comply, with major civil and criminal consequences to follow." U.S. Secretary of War Pete Hegseth said in a social media post that Anthropic delivered "a master class in arrogance and betrayal" and that Anthropic will continue to provide the Department of War with its services for a period of no more than six months to allow for a seamless transition to a better and more patriotic service, adding that "this decision is final."
