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

Gov. Gavin Newsom asked the Trump administration on Sunday to rescind its move to deploy 2,000 California National Guardsmen to Los Angeles to subdue immigration protests, accusing the White House of illegally overriding his authority and intentionally inflaming tensions with protesters.

A federal judge ruled Thursday that President Trump illegally federalized the California National Guard in response to the Los Angeles protests and ordered that the force be returned to the control of Democratic Gov.
