Trump's wide-ranging tariffs on Mexico, Canada and China divided lawmakers and world leaders over the weekend. President Donald Trump is expected to speak with Canadian Prime Minister Justin Trudeau and Mexican leaders today, two days after he announced he would impose sweeping tariffs on both countries and China.

Paul Krugman and Larry Summers are among the economists warning that Trump's tariffs may drive up prices, trigger job losses and erode trust in the US.

The one-month delay followed an announcement by Mexico that it would send 10,000 troops to secure its northern border.
