President Trump says he'll impose tariffs on Mexico and Canada on Tuesday. Mexico is working hard to persuade Trump to hold off on the threat.

In his third new tariff probe in a week, Trump signed a memo ordering Commerce Secretary Howard Lutnick to initiate a national security investigation into U.S. lumber imports under Section 232 of the Trade Expansion Act of 1962.
