LOS ANGELES – A U.S. judge on Thursday temporarily barred President Donald Trump from deploying National Guard troops in Los Angeles, finding that the Guard was unlawfully mobilized by Trump.

Judge Charles Breyer ordered the National Guard to return to the control of California Governor Gavin Newsom, who sued to restrict its activity. Breyer’s order will take effect at noon on Friday.

“The Court is troubled by the implication inherent in Defendants’ argument that protest against the federal government, a core civil liberty protected by the First Amendment, can justify a finding of rebellion,” Breyer wrote.

The Trump administration immediately appealed the judge’s order.

Trump summoned military troops to Los Angeles to support a civilian police operation over the objection of Newsom, an extraordinary and rarely used measure.

The ruling came hours after Department of Homeland Security Secretary Kristi Noem pledged to “liberate” Los Angeles at a press conference that was dramatically interrupted when federal agents dragged Democratic U.S. Senator Alex Padilla out of the room, forced him to the ground and handcuffed him.

The court battle and press conference scuffle underscored the political polarization generated by Trump’s approach to immigration enforcement and use of presidential power.

Trump summoned first the National Guard, then the Marines, to help federal police forces guard federal buildings from protesters and to protect federal immigration agents as they pick up suspected violators.

Trump has defended his decision, saying if he had not done so the city would be in flames. The protests so far have been mostly peaceful, punctuated by incidents of violence and restricted to a few city blocks.

Some 700 U.S. Marines will be on the streets of the city by Thursday or Friday, the military has said, to support up to 4,000 National Guard troops.
