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

President Donald Trump ordered the deployment of 2,000 National Guards troops to quell immigration protests in Los Angeles, overriding California Gov. Gavin Newsom’s objections in a rare move.

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