U.S. District Judge Charles Breyer, a former Watergate prosecutor, will decide whether Trump had the legal authority to federalize 4,000 California National Guard troops.

California Gov. Gavin Newsom asked a federal judge to quickly block the Trump administration's deployment of National Guard members and Marines to Los Angeles. Trump authorized the deployment to quell protests against federal immigration enforcement actions.

The temporary restraining order request alleges the deployment “escalates tensions and promotes (rather than quells) civil unrest.”

California on Tuesday asked a federal court for a temporary restraining order blocking the Trump administration's deployment of National Guard forces and U.S. Marines to Los Angeles.

The California Governor has sued the U.S. President over the mobilization of the National Guard, calling it “an unmistakable step toward authoritarianism.”

California asked a federal judge to immediately limit the Trump administration’s deployment of the state’s National Guard and US Marines amid protests in Los Angeles over the president’s immigration raids.
