Mexico and Canada retaliate against Trump’s tariffs

President Donald Trump launched a trade war Tuesday against America’s three biggest trading partners, drawing immediate retaliation from Mexico, Canada and China and sending financial markets into a tailspin.

Also, Trump will stand before a joint session of Congress on Tuesday to give an accounting of his turbulent first weeks in office as a divided nation struggles to keep pace, with some Americans fearing for the country’s future while others are cheering him on.
