LOS ANGELES — President Donald Trump has ordered an additional 2,000 National Guard troops and 700 Marines to Los Angeles. This military escalation is contrary to the preferences of local officials and Governor Gavin Newsom, and the police chief has expressed that it presents logistical challenges for managing protests safely.

The initial deployment of 2,000 National Guard troops ordered by Trump began arriving on Sunday, which experienced the most violence over three days of protests. The protests were fueled by outrage over Trump’s intensified immigration enforcement, which critics argue is tearing apart migrant families.

Monday’s demonstrations were notably more peaceful. Thousands participated in a rally at City Hall, while hundreds protested outside a federal complex that houses a detention center. Some immigrants are being held there following workplace raids conducted throughout the city.

Trump has described Los Angeles in dire terms that Mayor Karen Bass and Newsom say are nowhere close to the truth. They say he is putting public safety at risk by adding military personnel even though police say they don’t need the help.

Los Angeles Police Chief Jim McDonnell said in a statement he was confident in the police department’s ability to handle large-scale demonstrations and that the Marines’ arrival without coordinating with the police department presented a “significant logistical and operational challenge” for them.

Newsom called the deployments reckless and “disrespectful to our troops” in a post on the social platform X.

“This isn’t about public safety,” Newsom said. “It’s about stroking a dangerous President’s ego.”

The protests began Friday in downtown Los Angeles after federal immigration authorities arrested more than 40 people across the city. The smell of smoke hung in the air downtown Monday, one day after crowds blocked a major freeway and set self-driving cars on fire as police responded with tear gas, rubber bullets and flash-bang grenades.

U.S. officials said the Marine troops were deployed to protect federal property and personnel, including federal immigration agents. Trump’s Monday order put the National Guard members on active duty.

One U.S. official warned that the order was just signed and it could take a day or two to get troops moving. The official spoke on condition of anonymity to discuss troop movements.

Despite their presence, there has been limited engagement so far between the Guard and protesters while local law enforcement implements crowd control.

California Attorney General Rob Bonta filed a lawsuit over the use of National Guard troops following the first deployment, telling reporters in his announcement Monday that Trump had “trampled” the state’s sovereignty.

“We don’t take lightly to the president abusing his authority and unlawfully mobilizing California National Guard troops,” Bonta said. He sought a court order declaring Trump’s use of the Guard unlawful and asking for a restraining order to halt the deployment.

Trump said Monday that the city would have been “completely obliterated” if he had not deployed the Guard.

Bass criticized the deployment of National Guard troops and Marines as a “deliberate attempt” by the Trump administration to “create disorder and chaos in our city.”

She made a plea to the federal government: “Stop the raids.”

On Monday, thousands flooded the streets around City Hall for a union rally ahead of a hearing for arrested labor leader David Huerta, who was freed a few hours later on a $50,000 bond. Huerta’s arrest on Friday while protesting immigration raids has become a rallying cry for people angry over the administration’s crackdown. He is the president of the Service Employees International Union California, which represents thousands of the state’s janitors, security officers and other workers.

Early protests had a calm and even joyful atmosphere at times, with people dancing to live music and buoyed by Huerta’s release.

Protesters linked hands outside the downtown federal detention center where Huerta was being held in front of a line of police officers. Religious leaders joined the protesters, working with organizers at times to de-escalate moments of tension.

There was a heavy law enforcement presence in the few square blocks including the federal detention facility, while most in the immense city of some 4 million people went about their normal business on peaceful streets.

Chanting against a line of National Guard troops with Homeland Security officers behind them surrounding the federal buildings ramped up in the afternoon as people yelled, “Free them all!” and “National Guard go away.”

As the crowd thinned in the evening, police began pushing protesters away from the area, firing crowd-control munitions as people chanted, “Peaceful protest.”

Other protests took shape Monday afternoon across LA County. Outside a Los Angeles clothing warehouse, relatives of detained workers demanded at a news conference that their loved ones be released.

The family of Jacob Vasquez, 35, who was detained Friday at the warehouse, where he worked, said they had yet to receive any information about him.

“Jacob is a family man and the sole breadwinner of his household,” Vasquez’s brother, Gabriel, told the crowd. He asked that his last name not be used, fearing being targeted by authorities.

Several dozen people were arrested in protests throughout the weekend. Authorities say one was detained Sunday for throwing a Molotov cocktail at police and another for ramming a motorcycle into a line of officers.

McDonnell said police officers were “overwhelmed” by the remaining protesters, who included regular agitators who show up at demonstrations to cause trouble. He said the protests followed a similar pattern for episodes of civil unrest, with things usually ramping up in the second and third days.

The deployment appeared to be the first time in decades that a state’s National Guard was activated without a request from its governor, a significant escalation against those who have sought to hinder the administration’s mass deportation efforts.

The last time the National Guard was activated without a governor’s permission was in 1965, when President Lyndon B. Johnson sent troops to protect a civil rights march in Alabama, according to the Brennan Center for Justice.

In a directive Saturday, Trump invoked a legal provision allowing him to deploy federal service members when there is “a rebellion or danger of a rebellion against the authority of the Government of the United States.”
