President Donald Trump, in his first Oval Office meeting with new Canadian Prime Minister Mark Carney, said there was nothing Carney could say to him Tuesday that would convince the president to reduce tariffs on Canadian goods.

President Trump played nice when he came face-to-face with the new prime minister of Canada, the country he has spent months belittling.

The Canadian PM responds firmly as the president proposes a "wonderful marriage" of incorporating Canada into the US.
