NEW YORK — President-elect Donald Trump is threatening to impose sweeping new tariffs on Mexico, Canada and China as soon as he takes office as part of his efforts to crack down on illegal immigration and drugs.

In a pair of posts on his Truth Social site Monday evening, Trump wrote that, “On January 20th, as one of my many first Executive Orders, I will sign all necessary documents to charge Mexico and Canada a 25% Tariff on ALL products coming into the United States.”
