Trump has justified tariffs on goods from Canada, the top U.S. export market, by accusing it of failing to stop the cross-border flow of fentanyl, even though U.S. government data shows Canada accounts for only 1% of the fentanyl that enters the United States.

After Canada failed to strike a trade deal with Washington, the president raised tariffs on some Canadian exports this week.

On Thursday, Donald Trump announced sweeping new tariffs against U.S. trading partners that will go into effect next week. The announcement came on the same day that an appeals court grappled with the question of whether Trump’s tariffs are even legal.
