President Donald Trump will enforce tariffs on Tuesday against Canada and Mexico, but at what percentage, he has yet to decide, according to Commerce Secretary Howard Lutnick.

The president discussed tariffs during a White House event touting a $100 billion investment in the U.S. by Taiwan Semiconductor Manufacturing.

Mexico President Claudia Sheinbaum said Monday that her administration was waiting to see if U.S. President Donald Trump makes good on his threat to impose 25% tariffs on Mexican imports.
