SACRAMENTO, Calif. — California Gov. Gavin Newsom said Wednesday that his state will file a lawsuit challenging President Donald Trump’s authority to impose sweeping tariffs that have set off a global trade war.

The suit will argue that Trump’s use of the International Emergency Economic Powers Act to impose tariffs on Mexico, Canada and China or a 10% tariff on all imports is unlawful.

The lawsuit, which will be filed in the U.S. District Court for the Northern District of California, will also argue that enacting such tariffs requires approval from Congress.

Newsom says the tariffs in effect have resulted in inflated costs and billions of dollars in damage in California, which has the largest economy among U.S. states and is a massive exporter. — Associated Press
