Trump is sending 700 Marines, and another 2,000 National Guard members in addition to the 2,000 already deployed to help quell violent protests in California.

In announcing the lawsuit, Attorney General Rob Bonta called the president's move to federalize the National Guard an "infringement" on state sovereignty.

California Gov. Gavin Newsom (D) has argued that the deployment is “an illegal act, an immoral act, an unconstitutional act.”
