'No Kings' protest live updates: Cities prepare for anti-Trump rallies nationwide

Thirty mayors from the LA area joined together at a news conference to call on the raids to end.

LA Mayor Karen Bass again claimed that LA is "part of a national experiment" by the Trump administration "to determine how far the federal government can go in reaching in and taking over power" from state and local leaders.

Bass also highlighted the estimated $134 million spent to deploy the Marines and National Guard, saying, "all of our cities could use that money."

For many residents of the south LA city of Paramount -- one of the sites of protests -- "this has been one of the most devastating moments in recent memory," Paramount Mayor Peggy Lemons said, with some families now too afraid to leave their homes.

Huntington Park Mayor Arturo Flores, a Marine Corps veteran who served in Iraq and Afghanistan, said, "The militarization of immigration enforcement has no place in our neighborhoods and the deployment of Marines on U.S. soil is an alarming escalation that undermines the values of democracy."

"We stand against these fear-based tactics that target immigrant communities and erode public trust," he said, calling the administration's actions "political theater that is rooted in fear."

Mexican President Claudia Sheinbaum said 61 Mexican nationals have been detained in the LA raids and are now in detention centers.

There are currently 4,100 California National Guardsmen and 700 Marines in the greater Los Angeles area after President Donald Trump ordered them to protect federal buildings and federal law enforcement as protests opposed to ICE raids increased over the weekend.

Most of the attention has been focused on the crowd control assistance that these troops could provide around federal buildings, but Trump's memo calling up National Guardsmen also said they would "temporarily protect ICE and other United States Government personnel who are performing Federal functions, including the enforcement of Federal law."

On Tuesday, the X page for U.S. Immigration and Customs Enforcement (ICE) posted photos of California National Guardsmen on the scene of a detention being carried out by an ICE agent with the caption "Photos from today's ICE Los Angeles immigration enforcement operation."

The Posse Comitatus Act prevents active-duty U.S. military personnel from carrying out domestic law enforcement duties though that restriction can be lifted when a president invokes the Insurrection Act, which President Trump has not done.

In the photos, the National Guardsmen were armed with rifles but it was unclear if they were loaded with ammunition. ABC News has previously reported that while the federalized troops are carrying weapons, their guns will not have ammunition loaded in the chamber, according to U.S. officials. But they will carry ammunition as part of their regular uniforms that can be used in the rare case of needed self-defense.

A Wednesday morning crash in the Boyle Heights neighborhood of Los Angeles was being investigated as a possible assault with a deadly weapon involving federal agents who left the scene, authorities said.

The collision was reported at 10:47 a.m. in the 3700 block of Whittier Boulevard, a spokesperson for the Los Angeles Police Department told Los Angeles ABC station KABC.

No serious injuries were immediately reported.

Aerial video from KABC's chopper AIR7 showed LAPD officers and Los Angeles Fire Department firefighters at the crash site. No marked federal vehicles were visible.

Police did not specify which agency the agents involved in the crash worked for.
