Trump says Mexican tariffs will take effect, warns GOP pushback would be 'foolish'

Republicans and Democrats warned President Trump on Tuesday to quickly strike a border deal with Mexico and drop his threat of economically crippling tariffs, saying otherwise he faces an embarrassing vote to override his move in Congress.

Democrats were more enthusiastic about the battle, but even Republicans indicated that Mr. Trump would not have their support if he follows through on his threat to slap a 5% tariff on all Mexican goods Monday.

“We’re not fans of tariffs,” said Senate Majority Leader Mitch McConnell, Kentucky Republican.

Mr. Trump, traveling in London, told Republicans not to go wobbly on him.

“I don’t think they will do that. I think if they do, it’s foolish,” the president said during a press conference with British Prime Minister Theresa May.
