More than 20 states sue over Trump’s worldwide tariffs

By Canadian Press on March 5, 2026.

WASHINGTON — More than 20 states have filed a lawsuit challenging U.S. President Donald Trump’s latest worldwide tariffs.

Trump implemented the 10 per cent global duty last week after the United States Supreme Court struck down his previous tariff tool.

The president has threatened to increase those tariffs to 15 per cent but he has not yet signed an executive order putting that change in place.

These latest duties do not apply to goods compliant under the Canada-U.S.-Mexico Agreement on trade.

In the lawsuit, Democratic attorneys general and governors argue Trump is overstepping his power with his latest tariffs.

They say he can’t use Section 122 of the 1974 Trade Act, which has never previously been invoked, because it was intended to be used only in specific and limited circumstances.
