WASHINGTON—A handful of Republican senators broke with President Trump on trade policy, joining with Democrats to pass a resolution aiming to undo the president’s 25% tariff on Canadian imports.The 51-48 vote to approve the measure took place just hours after Trump imposed a 10% baseline tariff on all imports to the U.

The Senate voted Wednesday evening to revoke the emergency declaration President Donald Trump is using to impose duties on Canada, a bipartisan rebuke that came on the heels of his announcement of sweeping new global tariffs.
