President Donald Trump has deployed 4,000 National Guardsmen and 700 Marines to LA. But California Gov. Gavin Newsom and California Attorney General Rob Bonta are suing the Trump administration, saying they unlawfully "trampled over" California’s sovereignty when they federalized the California National Guard.

California sued Trump over the deployment, with the state attorney general arguing that the president had “trampled” the state’s sovereignty. California leaders accused Trump of fanning protesters’ anger, leading crowds to block off a major freeway and set self-driving cars on fire.
