(AP) — The Trump administration must stop deploying the California National Guard in Los Angeles and return control of the troops to the state, a federal judge ruled Wednesday.

U.S. District Judge Charles Breyer in San Francisco granted a preliminary injunction sought by California officials who opposed President Donald Trump’s extraordinary move to use state Guard troops without the governor’s approval to further his immigration enforcement efforts. But he also put the decision on hold until Monday.

California argued that conditions in Los Angeles had changed since Trump first took command of the troops and deployed them in June. The administration initially called up more than 4,000 California National Guard troops, but that number had dropped to several hundred by late October, with only a 100 or so troops remaining in the Los Angeles area.

But the Republican administration extended the deployment until February while also trying to use California Guard members in Portland, Oregon as part of its effort to send the military into Democratic-run cities despite fierce resistance from mayors and governors.

U.S. Justice Department lawyers said the administration still needed Guard members in the Los Angeles area to help protect federal personnel and property.
