In win for Canada, US appeals court strikes down much of Trump’s tariff tax agenda

Trump's 'fentanyl tariffs' on Canada and others have also been ruled illegal. Trump was clearly using the issue of fentanyl as a pretext to impose tariffs he wanted to impose anyway. You'll note that Trump finds any excuse he can to impose tariffs, and often shifts from one excuse to another. For example, he's claimed tariffs on Canada were due to fentanyl, military spending, the trade deficit (which is actually a U.S. trade surplus aside from heavily discounted Canadian energy exported to the U.S., which benefits the U.S. economy), and more.
