California Gov. Gavin Newsom had a brief victory in his lawsuit against President Trump, but an appeals court quickly blocked a federal judge's order.

SAN FRANCISCO (AP) — 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 there following protests in Los Angeles over immigration raids.

About 700 Marines and more than 4,000 National Guard have been deployed at the cost of $134 million. William Deverell is a professor of history at USC’s Dornsife College of Letters, Arts and Sciences.

President Donald Trump unlawfully federalized thousands of members of California’s National Guard and must return control of the troops to the state, a federal judge ruled Thursday.

Thousands of people nationwide have shown up at protests and rallies opposing ICE raids as unrest grows in response to the Trump administration's immigration crackdown.

Immigration raids have fueled days of protests, resulting in hundreds of arrests in Los Angeles as demonstrations have spread across the nation.

The California National Guard remain active on the streets of downtown Los Angeles on Friday after an appeals court put an order from a federal judge to remove the soldiers on hold only hours after it was decreed.

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.”

Homeland Security Secretary Kristi Noem pledged to carry on with the Trump administration’s immigration crackdown despite waves of unrest across the U.S.
