Trump’s tariffs on Canada face growing Republican revolt.

Wyden says there is “overwhelming support” for repealing the duties and that he is already talking to colleagues about legislation to challenge them. Some Republicans, particularly in states such as Michigan, Maine and Alaska, are also signaling unease over the economic impact.

The US imposed 50% tariffs on $27.6 billion worth of Canadian goods in August, hitting everything from clothes and school supplies to home goods and alcohol. Canada responded with counter-tariffs of 15%, 25% or 50% on about $27.6 billion of US imports.

The tariffs have raised prices for American families and hurt businesses that rely on Canadian inputs, particularly in the automobile and construction sectors.

Wyden believes the Canada tariffs offer the best chance to flip Republicans against Trump and potentially build enough support to override a presidential veto.

Even if Congress moves, Trump can veto any bill that seeks to roll back his tariffs. But Wyden argues that the political cost of defending them is rising, especially after the midterms showed voters are rejecting the policy.
