California is suing Trump over his tariff policy, claiming it is illegal and damaging to the economy

On April 16, the office of California Governor Newsom issued a statement on Trump's tariff measures, saying that the state will file a lawsuit to seek to stop Trump's tariff policy. California's major industries, from Silicon Valley to agriculture, rely heavily on global trade, and therefore could lose billions of dollars due to tariffs. "President Trump's illegal tariff measures are causing chaos to California families, businesses, and our economy - driving up prices and threatening jobs," Newsom said in the statement. The lawsuit is Newsom's most direct legal challenge to Trump's agenda since he returned to the presidency in January. Mr. Newsom's argument is against the International Economic Emergency Powers Act, which Mr. Trump uses to impose tariffs without congressional approval. The Democrat argues that Mr. Trump does not have the authority to impose tariffs under that law, echoing a similar lawsuit filed by a group of US companies on Monday.
