Trump stormed out of the G7 summit in Canada on Monday, ditching the final sessions and sending Air Force One back to Washington without explaining a thing to the press. That vacuum didn’t last long though—Emmanuel Macron,

The 2018 summit ended with Trump assailing his Canadian hosts on social media as he departed on Air Force One, saying he had instructed the U.S. officials who remained in Quebec to oppose the G7 joint statement endorsed by the leaders of Japan, France, the United Kingdom, Italy, Germany and, of course, Canada.

Trump's relationship with Canadian Prime Minister Mark Carney will be in the spotlight at the G7, after past conflict with his predecessor, Justin Trudeau.
