The curfew in a part of downtown Los Angeles will remain in effect Saturday night as multiple protests are expected in the city, LA Mayor Bass said.

"Hundreds of additional personnel are mobilized and proactively positioned to keep people safe and to protect property,” she said.

She said Friday’s protests were peaceful with very few arrests.

"We have zero tolerance for anyone who damages property or puts officers or people at risk," Bass stressed, pleading, "Please, please do not give the administration an excuse to intervene. Let's make sure we show the world the best of Los Angeles, and our country."

LAPD Chief Jim McDonnell added, "If you're here in Los Angeles today to make your voice heard through peaceful demonstrations, we are here to protect you. But if you come with the intent to commit crime, damage property or harm others, including our officers, you will be arrested. ... We're asking everyone who plans to participate in today's events to do so peacefully and respectfully."

Since June 7, the LAPD said it's made 523 arrests related to protest activity.

National Guardsmen have carried out 26 missions since they were deployed to Los Angeles, Maj. Gen. Scott Sherman of the National Guard said. A handful of those assignments have been to guard facilities and the remaining have been missions protecting ICE on raids, he said.

Sherman had told ABC News and The Associated Press in a joint interview on Wednesday that 500 of the 4,000 National Guardsmen assigned to LA had been specifically trained to work with these ICE teams. Now that the Guardsmen who had been protecting the federal buildings are being replaced by 200 Marines, those Guardsmen will be trained to working on ICE raids.

"I would like to emphasize that the soldiers will not participate in law enforcement activities," Sherman said. "Rather, they'll be focused on protecting federal law enforcement personnel."

Sixty demonstrators, part of a veterans protest against militarism, were arrested at the Supreme Court on Friday night and will be charged with unlawful demonstration and crossing a police line, Capitol police said. Some will also be charged with assault on a police officer and resisting arrest, police said.

"A few people pushed the bike rack down and illegally crossed the police line while running towards the Rotunda Steps," Capitol police said in a statement.

Brittany Ramos DeBarros, a former Army captain who was one of the organizers of the event, told ABC News that although they planned this before the protests in Los Angeles, they now also plan on calling attention to the Trump administration's deployment of the military to the LA protests.

“We need to see more courage, more resistance, to the terrifying consolidation of authoritarianism that we're seeing right now, particularly as we're seeing the Marines be mobilized in our own cities,” Ramos DeBarros said.

“It's not an accident that Trump is about to have tanks rolling down our streets here in D.C. [at Saturday’s Army anniversary parade] while he has the military also terrorizing immigrants in LA,” she said.

The Department of Homeland Security confirmed to ABC News that it issued new guidance to pause most raids on farms, restaurants, and hotels, after Trump earlier this week shifted his stance on targeting undocumented workers in those industries.

"Effective today, please hold on all work site enforcement investigations/operations on agriculture (including aquaculture and meat packing plants), restaurants and operating hotels," senior ICE official Tatum King wrote in an email to leaders of the ICE department that generally carries out criminal investigations.

The email says that investigations involving "human trafficking, money laundering, drug smuggling into these industries are OK."

The new guidance was first reported by the New York Times.

"We will follow the president's direction and continue to work to get the worst of the worst criminal illegal aliens off of America's streets," DHS spokesperson Tricia McLaughlin said in a statement on ABC News.

This comes after Trump publicly acknowledged that those industries have been hurt by his deportation agenda.
