Trump warns Congress while threatening Canada

President Trump said in a Saturday tweet that there is "no political necessity" to include Canada in a new trade deal between the U.S. and Mexico — and he threatened to terminate NAFTA entirely if Congress interferes with negotiations.

The state of play: In the midst of ongoing negotiations between the U.S. and Canada, Trump said he is refusing to grant Canada any concessions in negotiations. Talks between the two sides are scheduled to resume on Wednesday.
