Protests live updates: Marines make 1st temporary detention in LA

Trump administration border czar Tom Homan refuted claims that he was going to arrest Los Angeles Mayor Karen Bass and California Gov. Gavin Newsom, telling Fox News that an interview from this weekend was taken out of context.

"The reporter asked about, 'Could Governor, Governor Newsom, or Mayor Bass, be arrested?' I said, 'Well, no one's above the law, if they cross the line and commit a crime. Absolutely they can,'" Homan explained. "So there was no discussion about arresting Newsom."

Homan asserted that he was speaking broadly that if anyone "crosses the line," they will be prosecuted.

"You can protest. You got your First Amendment rights. But when you cross that line, you put hands on an ICE officer, or you destroy property, or ICE says that you're impeding law enforcement … that's a crime, and that the Trump administration is not going to tolerate," he said.

President Donald Trump offered similar comments on Sunday, saying if California officials "stand in the way of law and order, yeah, they will face charges."

California Gov. Gavin Newsom said the state is suing the Trump administration, claiming President Donald Trump illegally federalized the National Guard.

The clashes between protesters and law enforcement "is exactly what Donald Trump wanted," Newsom wrote on social media Monday morning.

"He flamed the fires and illegally acted to federalize the National Guard," Newsom said. "The order he signed doesn’t just apply to CA. It will allow him to go into ANY STATE and do the same thing. We’re suing him."

President Donald Trump in a series of social media posts said the National Guard should be brought in "right now" to help deal with protesters in Los Angeles.

"Jim McDonnell, the highly respected LAPD Chief, just stated that the protesters are getting very much more aggressive, and that he would "have to reassess the situation," as it pertains to bringing in the troops, Trump said in one post.

He added, "He should, RIGHT NOW!!! Don't let these thugs get away with this. MAKE AMERICA GREAT AGAIN!!!"

Trump was referring to McDonnell's Sunday night press conference, where he said, "this thing has gotten out of control" and would now have to make a "reassessment" about requesting the National Guard.
