National Guard troops have begun arriving in Los Angeles on orders from President Donald Trump to stamp out protests that have broken out in recent days against federal immigration authorities seeking to carry out deportations in the region.

The members of California’s National Guard were seen staging early Sunday at the federal complex in downtown Los Angeles that includes the Metropolitan Detention Center, where confrontations occurred the last two days.

Trump says he is deploying 2,000 California National Guard troops to Los Angeles — over the objections of Gov. Gavin Newsom.

Confrontations broke out on Saturday near a Home Depot in the heavily Latino city of Paramount, south of Los Angeles, where federal agents were staging at a Department of Homeland Security office nearby. Agents unleashed tear gas, flash-bang explosives and pepper balls, and protesters hurled rocks and cement at Border Patrol vehicles. Smoke wafted from small piles of burning refuse in the streets.

Tensions were high after a series of sweeps by immigration authorities the previous day, including in LA’s fashion district and at a Home Depot, as the weeklong tally of immigrant arrests in the city climbed past 100. A prominent union leader was arrested while protesting and accused of impeding law enforcement.

The White House announced that Trump would deploy the Guard to “address the lawlessness that has been allowed to fester.”

Newsom, a Democrat, said in a post on the social platform X that it was “purposefully inflammatory and will only escalate tensions.” He later said the federal government wants a spectacle and urged people not to give them one by becoming violent.

In a signal of the administration’s aggressive approach, Defense Secretary Pete Hegseth threatened to deploy the U.S. military.

“If violence continues, active-duty Marines at Camp Pendleton will also be mobilized — they are on high alert,” Hegseth said on X.

Trump’s order came after clashes in Paramount and neighboring Compton, where a car was set on fire. Protests continued into the evening in Paramount, with several hundred demonstrators gathered near a doughnut shop, and authorities holding up barbed wire to keep the crowd back.

Crowds also gathered again outside federal buildings in downtown Los Angeles, including a detention center, where local police declared an unlawful assembly and began to arrest people.
