WASHINGTON (AP) — President Donald Trump issued a memo Friday that calls for the U.S. military and national security agencies to accelerate their use of artificial intelligence, while acknowledging the need to protect civil liberties and maintain oversight over autonomous weapon systems.

The memo comes at a time of growing anxiety over AI in American society, from replacing people’s jobs to helping to identify targets on the battlefield. The Trump administration has been pushing to unleash the power of AI for the U.S. military, while some military leaders and companies that contract with the Pentagon have been noting caution and calling for guardrails.

Trump’s memo addressed much of his Cabinet, including the secretaries of defense and homeland security as well as the attorney general and director of national intelligence.
