Internet reports that California Governor Newsom's office issued a statement on Trump's tariff measures, saying that the state would file a lawsuit to seek to stop Trump's tariff policy. California relies heavily on global trade for major industries from Silicon Valley to agriculture, and 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 a statement. The lawsuit is Newsom's most direct legal challenge to Trump's policy agenda since Trump took office again in January this year. Newsom's argument is aimed at the U.S. International Economic Emergency Powers Act, which is based on which Trump collects tariffs without congressional approval. The Democrat believes Trump has no authority to impose tariffs under the law, consistent with a similar lawsuit filed by a group of U.S. companies on Monday.
