Canadian Prime Minister Mark Carney met with President Trump at the Oval Office Tuesday, where he rejected Trump’s call to annex Canada as the “51st state.”

Prime Minister Mark Carney: “And having met with the owners of Canada over the course of the campaign last several months, it’s not for sale, won’t be for sale, ever.”

In response to Carney’s remarks, Trump said, “Never say never,” while Carney mouthed the words “never, never, never.” Trump also said during Tuesday’s Oval Office meeting that nothing Carney could say would persuade him to lift U.S. tariffs on Canada.
