LOS ANGELES – Leaders in Los Angeles have implemented a downtown curfew effective through Wednesday morning due to demonstrations opposing President Donald Trump’s immigration policies. Meanwhile, the governor criticized Trump for creating a “military dragnet” across Los Angeles, the nation’s second-largest city, by increasing National Guard presence.

Democratic Governor Gavin Newsom has requested a court order to immediately halt military support for federal immigration officers. Guardsmen have been stationed to protect these agents as they conduct arrests, which Newsom argues could escalate tensions and trigger public disorder. The judge delayed ruling, allowing the administration to continue its activities until a Thursday hearing.

This adjustment brings troops nearer to participating in law enforcement activities like deportations, in line with Trump’s immigration policy promises. The Guard can temporarily hold individuals who assault officers, but actual arrests would still be carried out by law enforcement agencies.

Trump has activated more than 4,000 National Guard members and 700 Marines over the objections of city and state leaders, though the Marines have not yet been spotted in Los Angeles and Guard troops have had limited engagement with protesters. They were originally deployed to protect federal buildings.

As the curfew went into effect Tuesday night, a police helicopter flew over downtown federal buildings that have been the center of protests and ordered people to leave the area. Riot police on horses and foot surrounded a group of a few hundred that had gathered in the area, shouting: “Move!” Most of the protesters scattered, with some regrouping and refusing orders to disperse.

Officials said the curfew was necessary to stop vandalism and theft by agitators looking to cause trouble.

Demonstrations have spread to other cities nationwide, including Dallas and Austin, Texas, Chicago and New York, where a thousand people rallied and multiple arrests were made.

In Texas, where police in Austin used chemical irritants to disperse several hundred demonstrators Monday, Republican Gov. Greg Abbott’s office said Texas National Guard troops were “on standby” in areas where demonstrations are planned, Abbott spokesperson Andrew Mahaleris said Tuesday evening.

Guard members were deployed to San Antonio, according to assistant police chief Jesse Salame. He said he did not know how many were sent or details on the deployment.

LA mayor puts curfew in place

Los Angeles Mayor Karen Bass declared a local emergency on the fifth day of protests and said the curfew will run from 8 p.m. Tuesday until 6 a.m. Wednesday. She said it was expected to last for several days.

“We reached a tipping point” after 23 businesses were looted, Bass said during a news conference Tuesday.

The curfew covers a 1 square mile (2.5 square kilometer) section of downtown that includes the area where protests have occurred since Friday. The city of Los Angeles encompasses roughly 500 square miles (nearly 2,300 square kilometers).

The curfew doesn’t apply to residents who live in the designated area, people who are homeless, credentialed media or public safety and emergency officials, according to Los Angeles Police Chief Jim McDonnell.

McDonnell said “unlawful and dangerous behavior” had been escalating since Saturday.

“The curfew is a necessary measure to protect lives and safeguard property following several consecutive days of growing unrest throughout the city,” McDonnell said.

Trump says he’s open to using Insurrection Act

Trump left open the possibility of invoking the Insurrection Act, which authorizes the president to deploy military forces inside the U.S. to suppress rebellion or domestic violence or to enforce the law in certain situations. It’s one of the most extreme emergency powers available to a U.S. president.

“If there’s an insurrection, I would certainly invoke it. We’ll see,” he said from the Oval Office.

Later the president called protesters “animals” and “a foreign enemy” in a speech at Fort Bragg ostensibly to recognize the 250th anniversary of the U.S. Army.

Trump has described Los Angeles in dire terms that Bass and Newsom say are nowhere close to the truth.

In a public address Tuesday evening, Newsom called Trump’s actions the start of an “assault” on democracy.

“California may be first, but it clearly will not end here. Other states are next,” he said.

Newsom warned people against inciting violence, but urged them to stand up to the president’s actions.

“What Donald Trump wants most is your fealty, your silence. To be complicit in this moment,” he said. “Do not give it to him.”

The protests began Friday after federal immigration raids arrested dozens of workers in Los Angeles. Protesters blocked a major freeway and set cars on fire over the weekend, and police responded with tear gas, rubber bullets and flash-bang grenades.

The demonstrations have been mostly concentrated downtown in the city of 4 million. Thousands of people have peacefully rallied outside City Hall and hundreds more protested outside a federal complex that includes a detention center where some immigrants are being held following workplace raids.

Despite the protests, immigration enforcement activity has continued throughout the county, with city leaders and community groups reporting ICE present at libraries, car washes and Home Depots. School graduations in Los Angeles have increased security over fears of ICE action and some have offered parents the option to watch on Zoom.

McDonnell said that police had made 197 arrests on Tuesday, including 67 who were taken into custody for unlawfully occupying part of the 101 freeway.

Several businesses were broken into Monday, though authorities didn’t say if the looting was tied to the protests.

The vast majority of arrests have been for failing to disperse, while a few others were for assault with a deadly weapon, looting, vandalism and attempted murder for tossing a Molotov cocktail. Seven police officers were reportedly injured, and at least two were taken to a hospital and released.

Defense Secretary Pete Hegseth suggested Tuesday that the use of troops inside the U.S. will continue to expand.

The Pentagon said deploying the National Guard and Marines costs $134 million.
