The president faces at least three other legal challenges to his tariffs, though major industries caught in the tariff crossfire have held off from any legal action for now.

California Governor Gavin Newsom said that he has initiated a lawsuit against Donald Trump’s administration challenging the president’s authority to impose tariffs. On his podcast posted today, Newsom said that the lawsuit will assert “that Trump does not have the unilateral authority to impose one of the largest tax increases in history.

“Trump’s tariffs are the single largest tax increase in our lifetime, and they’re jamming Californians with higher prices on groceries, medicine and cars,” said Assembly Speaker Robert Rivas, D-Hollister, in a statement. “We’re protecting our residents — and all American families — from unlawful economic chaos.”
