President Donald Trump jolted the Group of Seven summit Monday evening when he posted on Truth Social that “everyone should immediately evacuate Tehran,” repeating in all caps his long-held stance that “IRAN CAN NOT HAVE A NUCLEAR WEAPON.” Minutes later the White House announced the president would leave Banff, Canada, a day early and convene the National Security Council in Washington. A press charter departed Calgary just after 11 p.m. Eastern with senior advisers, while U.S. military aircraft stood ready at Joint Base Andrews to fly Cabinet principals directly to the Situation Room if needed.
