Trump invoked a law called the International Emergency Economic Powers Act on April 2 to set a blanket 10% tariff on all imports and, initially, additional duties on almost 60 countries that have the largest trade surpluses with the US.

Gov. Gavin Newsom on Wednesday announced a lawsuit alleging that President Trump lacks the authority to enact the international tariffs without the support of Congress.
