MSNBC’s Lawrence O’Donnell explains how Donald Trump backed down on his tariffs against Canada and Mexico after Canadian Prime Minister Trudeau rebuked his tariff lies in speaking directly to the American people.

Just after the stock market had its second freak-out in a row, just after businesses around the country planned “what are we going to do now” board meetings, just after Canada and China retaliated with tariffs of their own, just after Republican members of Congress pleaded with the administration to dial down its trade policy, just after the International Chamber of Commerce warned of a Great-Depression-like economic catastrophe, the Trump administration appeared to change its mind on its massive tariffs on its biggest trading partners.
