Protesters converged in downtown Los Angeles for the fourth straight day of anti-ICE demonstrations on Monday, hours after hundreds of National Guard troops arrived in the area after President Trump ordered their deployment following days of violent clashes. 

The Los Angeles Police Department confirmed that 50 people were arrested over the weekend following protests that overtook several blocks in downtown LA, including a stretch of the 101 Freeway. A spokesperson for the department said people arrested were booked for different crimes, including failure to disperse, assault with a deadly weapon on a police officer, looting and arson. The LAPD also said five officers were injured during the weekend events. Three were treated at the scene and two suffered minor injuries. 

The LAPD and the LA County Sheriff's Department declared the gatherings unlawful and ordered people to go home.

On Sunday afternoon, officers from the LAPD and members of the National Guard were seen wearing riot gear outside the Metropolitan Detention Center in front of a large group of protesters. SkyCal captured images of soldiers firing what appeared to be tear gas and non-lethal rounds into crowds trying to disperse them. Several buildings, street signs and public buses were vandalized with anti-ICE messages, including police patrol vehicles.

 posted on X that people who "lay a hand" on law enforcement officers will be prosecuted to the full extent of the law.  

Protests began on Friday evening after immigration enforcement operations were conducted in the Westlake District and in downtown and South LA, which led to the arrest of dozens of unauthorized immigrants. ICE officials confirmed four federal search warrants were served at three locations.

Crowds gather downtown again

For the fourth consecutive day, large crowds of protesters gathered in downtown Los Angeles, with most of their demonstration taking place outside of the Robert Young Federal Building. 

Hundreds of people rallied out front, separated from the building's entrance by a line of National Guard troops holding riot shields. 

Though Monday afternoon's gathering was mostly peaceful, the situation briefly escalated at around 5:30 p.m., when LAPD officers began to push the crowd from the area and there were minor clashes between some of the people in the crowd and police.

At times, officers fired rubber munitions and pepper-filled rounds in an attempt to disperse the demonstrators, which was witnessed by CBS News Los Angeles reporters at the scene. 

As of 9:30 p.m. most of the crowd appeared to have cleared from the downtown area, though a crowd of several hundred was gathered at 2nd Street and San Pedro Street, where they were met by a line of law enforcement vehicles that stretched three city blocks. 

The situation once again escalated for a small amount of time, with some people hurling fireworks in the directions of officers and even pushing a large trash bin towards their skirmish line. At the same time, officers were seen deploying smoke-filled canisters towards the crowd. 

At around 11:30 p.m., though most of the people had cleared from the area, some continued to move, setting fires and forming barricades with objects they found on the street. One car outside of a church was set on fire near an intersection where a hammer was used to break a curb apart, with people grabbing the chunks of broken cement. 

This followed three days of protests that escalated into violence. In each instance, LAPD officials declared unlawful assembly and issued dispersal orders for the crowds that blocked the 101 Freeway, lit fires, destroyed Waymo vehicles and graffitied dozens of buildings in the area, including the LAPD Headquarters and the federal courthouse.

At around 3:20 p.m., L.A. police once again announced that the department was on "tactical alert" meaning every uniformed officer working was required to remain on shift and assist with the developing situation. 

In response to the weekend's events, LAPD officials shared a statement on their crowd dispersal methods. 

"During the course of the demonstrations, protesters erected barricades and continued to launch projectiles at officers," said a statement from the department. "The use of handheld CS gas canisters was authorized to disperse the hostile crowd. The use of the chemical agent was effective, and the barricades were dismantled. In addition, multiple deployments of less-lethal munitions were necessary to manage the crowd and prevent further harm to people or property. Over 600 rounds of less-lethal munitions were used."

Cleanup was already underway come Monday morning.

Administration orders U.S. military to Los Angeles

A U.S. defense official told CBS News on Monday that 700 active duty Marines based in Twentynine Palms were activated and deployed to join the nearly 300 National Guard troops already in L.A., who received orders from Mr. Trump on Saturday in response to protests. 

A Presidential Memoranda said that 2,000 National Guard troops were deployed to the area, but on Sunday the U.S. military's Northern Command said that 300 were actively in the Los Angeles area. 

He posted on criticizing Gov. Gavin Newsom and Mayor Karen Bass for not being able to handle to situation. He posted again on Sunday, furthering his statements, saying Newsom and Bass should "apologize to the people of Los Angeles for the absolutely horrible job that they have done, and this now includes the ongoing L.A. riots."

LAPD Chief McDonnell shared a statement after learning that U.S. Marines were also being sent to the city. 

"The LAPD has not received any formal notification that the Marines will be arriving in Los Angeles. However, the possible arrival of federal military forces in Los Angeles—absent clear coordination—presents a significant logistical and operational challenge for those of us charged with safeguarding this city," the statement said. "The Los Angeles Police Department, along with our mutual aid partners, have decades of experience managing large-scale public demonstrations, and we remain confident in our ability to do so professionally and effectively."

On Monday afternoon, Newsom posted on X that he was informed of an additional 2,000 National Guards troop being deployed. 

"The first 2,000? Given no food or water. Only approx. 300 are deployed — the rest are sitting, unused, in federal buildings without orders," . "This isn't about public safety. It's about stroking a dangerous President's ego.This is Reckless. Pointless. And Disrespectful to our troops."

Pentagon chief spokesman Sean Parnell confirmed that more troops would respond to the city, joining the thousands already assigned to the region.

Newsom's office confirmed on Saturday that he spoke with Mr. Trump for about 40 minutes, although it's unclear if they spoke before or after Mr. Trump announced the deployment.  

On Monday, Newsom and California Attorney General Rob Bonta filed a lawsuit against the Trump Administration. At a virtual news conference, Bonta said the lawsuit is in response to Mr. Trump's and Defense Secretary Pete Hegseth over their orders to "federalize the California National Guard."

"President Trump's order calling federalized National Guard troops into Los Angeles — over the objections of the Governor and local law enforcement — is unnecessary and counterproductive. It's also deeply unfair to the members of the National Guard who are hard at work every day protecting our state, preparing for and responding to emergencies, and training so that, if called, they can fight our nation's wars," Bonta said.  

The attorney general added that the lawsuit argues that Mr. Trump's orders exceed the federal government's authority under the Tenth Amendment. 

The governor said later Monday that he would also sue Mr. Trump over the deployment of U.S. Marines. 

"U.S. Marines serve a valuable purpose for this country -- defending democracy. They are not political pawns. The Secretary of Defense is illegally deploying them onto American streets so Trump can have a talking point at his parade this weekend," said his . "It's a blatant abuse of power. We will sue to stop this."

CBS News has reached out to Bonta and Newsom for comment on the second potential lawsuit but has not yet heard back. 

Immigration enforcement operations across Los Angeles

Agents from Homeland Security Investigations, the Drug Enforcement Agency and the FBI executed several search warrants in the Westlake District, downtown and South LA on Friday. ICE officials confirmed to CBS News that at one operation site, 44 unauthorized immigrants were taken into custody.

Along with those dozens of arrests, was David Huerta, the president of Service Employees International Union-United Services Workers West. He was taken into custody after he deliberately obstructed" federal officers by blocking their vehicle during the operation, according to U.S. Attorney Bill Essayli. 

As videos spread on social media about the operations, crowds of people began gathering, trying to stop agents from putting people into federal vehicles. On Friday night, a large demonstration formed outside the Federal Building in downtown LA after protesters learned that detainees were allegedly being held inside.

A federal law enforcement official with knowledge of the operations told CBS News that ICE requested assistance from LAPD multiple times over the course of Friday night. That same official said it took local authorities more than two hours to honor that request, although a senior city official in L.A. told CBS News that it took LAPD 55 minutes to respond, not two hours.

There were also protests in Paramount and Compton on Saturday, where a vehicle was set on fire in the middle of the street. 

On Monday, ICE activity induced fear in Huntington Park, according to city officials who held a press conference in the afternoon.

"This city is aware of the presence of Immigration and Customs Enforcement agents that conducted an operation this morning," said Huntington Park Mayor Arturo Flores. "The reason for this press conference ... is to denounce the actions being taken by the federal government. I want to make it very clear: the Trump Administration's immigration policy was centered around public safety. The actions that we're seeing take place, not only in Los Angeles, but throughout the region, are counterintuitive to that narrative."

He said that city officials have not yet received information on arrests during the operation, which took place at around 7:30 a.m. at a Home Depot on Slauson Avenue. 

LAUSD superintendent on ICE operations

At a news conference Monday morning, LA Unified School District Superintendent Alberto Carvalho told reporters that his office remains committed to keeping students and schools safe, following an increase in immigration enforcement operations. 

Carvalho explained that there were two recent incidents where federal vans were reported a few blocks from two LAUSD campuses. He said agents did not attempt to enter either school, but the district is interpreting those "actions as acts of intimidation."

The superintendent also said that as graduation season is underway, there will be an increased presence of LAUSD police at school events. He said parents should not be afraid of attending school celebrations out of fear that federal agents will be present. 

"I have directed our own police force to redouble their efforts and establish perimeters of safety around graduation sites and to intervene and interfere with any federal agency that may want to take action during these joyous times that we call graduation," Carvalho said.

Demonstrations take place throughout California

Apart from the demonstrations taking place in Los Angeles, protesters also took to the streets in other cities up and down the Golden State. 

In Santa Ana on Monday, a large crowd of people gathered outside of the complex of federal buildings in the downtown area, where the demonstration heightened into law enforcement deploying crowd dispersal methods like smoke-filled canisters and pepper balls. CBS News Los Angeles reporters at the scene said that people in the area were throwing projectiles towards authorities prior to this.

At times, with the CBS helicopter overhead, cans of tear gas were launched by federal agents at the feet of demonstrators who moved closer to the building. At least one person was seen being taken into custody in a parking lot across from the federal building. 

"When a peaceful demonstration escalates into rocks, bottles, mortars, and fireworks being used against public service personnel, and property is destroyed, it is no longer a lawful assembly. It is a violation of the law," said a statement from Santa Ana Police Chief Robert Rodriguez. "We will not stand by while our City is put at risk. Santa Ana Police officers, along with our mutual aid partners, are actively working to restore order. We urge everyone to go home."

A crowd of hundreds also gathered outside of the federal courthouse in Santa Ana, where they held signs denouncing the immigration operations.

A similar scene unfolded in San Diego over the weekend, where outside of a restaurant where an immigration operation took place earlier in the month.

Police in San Francisco issued a statement late Monday saying, "Thousands participated in demonstrations today that were overwhelmingly peaceful. At the very end of the night, two small groups broke off and committed vandalism and other criminal acts. Detained multiple individuals who refused to comply and made arrests." The statement referred to protests at the city's Civic Center and in the Mission District.

The protests came just a day after 154 people were arrested in San Francisco during demonstrations denouncing ICE raids.

There were also protests in Dallas, where local community leaders planned the events to solidarity with Los Angeles.
