The 9th U.S. Circuit Court of Appeals on Thursday temporarily blocked a federal judge's order that directed President Donald Trump to return control of National Guard troops to California after he deployed them in response to protests in Los Angeles over immigration raids.

California Governor Gavin Newsom offered some cutting words on social media for President Donald Trump Thursday as he battled to retain command of the state’s National Guard. He might have spoken too soon.

Their clash over Trump’s deployment of military forces for anti-ICE protests in Los Angeles is far from the first time the two leaders have butted heads.

"By calling forth troops...the President flouts the vision of our Founders," read an amicus brief filed by 21 states.

The state of California had sought to stop the president from sending National Guard troops without the governor’s approval.

Senior U.S. District Court Judge Charles R. Breyer said he was “trying to figure out where the lines are drawn.”
