'No Kings' protests: Tensions rise in LA as crowd hurls concrete, police allege

About 700 Marines are still undergoing civil disturbance training at Naval Weapons Station Seal Beach in Orange County, said Maj. Gen. Scott Sherman, head of the task force that's overseeing the deployment of the National Guard and Marines to Los Angeles.

About 700 Marines are still undergoing civil disturbance training at Naval Weapons Station Seal Beach in Orange County.

Sherman wouldn't speculate about when the Marines might join the 2,000 or so Guard troops that have been deployed in downtown areas to protect federal buildings during sometimes violent demonstrations against President Trump's immigration crackdown.

"Our mission is to protect federal agencies, our federal partners, their personnel, as they conduct their federal mission," Sherman said.

Another 2,000 Guard soldiers are on duty and stationed at Joint Forces Training Base in Los Alamitos.

With migrant communities already living in fear amid the Trump administration's immigration crackdown, ICE raids in downtown Los Angeles sparked days of protests.

Several people protesting ICE detentions were arrested in downtown Manhattan on Wednesday. Officers began detaining people after the protest, which started in Foley Square near City Hall, began moving down Broadway before being stopped by police at the intersection of Broadway and Duane.

The arrests appeared to take place after protesters did not clear a crosswalk when ordered to by police.

Hundreds of protesters remain in the area, chanting behind barriers, with dozens of officers standing by.

An immigrant in Los Angeles has been charged with one count of assault of a federal employee for allegedly spitting on an Immigration and Customs Enforcement officer.

The Department of Justice announced on Wednesday that the suspect, Omar Pulido Bastida, 41, faces a statutory maximum sentence of eight years in federal prison for the alleged crime.

The incident happened earlier this week when the officer was executing a warrant for Bastida's arrest, according to the DOJ. Bastida allegedly spat at the officer through an iron security gate on his door.

ICE officials eventually forced entry into the residence and arrested Bastida.

"This defendant found out the hard way: When you spit, we hit - with a felony charge," said United States Attorney Bill Essayli. "Law enforcement officers risk their lives and safety to uphold the law. To treat them with disrespect, like this defendant did, mocks our great nation and such behavior will be punished accordingly."
