President Trump and Canadian Prime Minister Mark Carney spoke to reporters as they met in the Oval Office to discuss U.S.-Canada trade and military relations, and the prime minister's first trip out of the country since becoming Canada's top legislator. Mr. Carney reiterated his earlier stance that Canada was "not for sale," despite President Trump's reiteration of his desire for the nation to become the 51st state. The two talked about the ongoing dispute on tariffs, and specifically those levied on automakers and suppliers who work on both sides -- and across -- the border. President Trump and Secretary of State Marco Rubio also talked briefly about an update on the status of Iran-backed Houthi rebels in Yemen, which they said had signaled their willingness to cease fighting with U.S. and Israeli-backed forces.
