California Gov. Gavin Newsom (D) said he will sue the Trump administration on Monday over the president's deployment of the National Guard after a violent night of anti-immigration enforcement protests.

Newsom told MSNBC on Sunday evening that the lawsuit would challenge President Trump's federalization of the California National Guard without the governor's consent, which has rarely occurred in U.S. history.

“Donald Trump has created the conditions you see on your TV tonight. He’s exacerbated the conditions. He’s, you know, lit the proverbial match. He’s putting fuel on this fire, ever since he announced he was taking over the National Guard — an illegal act, an immoral act, an unconstitutional act,” Newsom said.

“And we’re going to test that theory with a lawsuit tomorrow,” he added.

Newsom said that Trump's executive order "specifically notes — and under what the [Department of Defense] did — is they had to coordinate with the governor of the state. They never coordinated with the governor of the state."

"We have no problem, working collaboratively in a mutual aid system with local law enforcement. But there’s a protocol, there’s a process. He didn’t care about that," Newsom added, referring to Trump. "And the worst part, he completely lied."

Protests and rioting in Los Angeles against U.S. Immigration and Customs Enforcement agents' arrests of illegal aliens entered a third day Sunday, with hundreds flooding the 101 freeway in downtown Los Angeles and bringing traffic to a standstill.

Police said in a post on X that California Highway Patrol officers are attempting to disperse the demonstrators off the southbound section of the freeway. LAPD also said cars had been set on fire in a historic neighborhood, causing authorities to declare an unlawful assembly.

The National Guard deployed to Downtown Los Angeles on Sunday, using chemical agents and designating certain blocks of the city as unlawful assembly zones as evening neared, Newsweek reported.

The governor told MSNBC that Trump's post on Truth Social early Sunday, saying the National Guard had done a "great job," was before they had been deployed.

“It’s Orwellian, simply lying to people, unconstitutional, illegal act, his mess. We’re trying to clean it up,” Newsom added.

He also responded to border czar Tom Homan saying that he wouldn't rule out arresting Newsom or Los Angeles Mayor Karen Bass (D) if they interfered with his immigration efforts.

“Come after me, arrest me. Let’s just get it over with, tough guy, you know? I don’t give a damn. But I care about my community. I care about this community,” Newsom said.

“The hell are they doing? These guys need to grow up. They need to stop and we need to push back. And I’m sorry to be so clear, but that kind of bloviating is exhausting,” he added. “So, Tom, arrest me. Let’s go.”

White House spokeswoman Abigail Jackson told NewsNation that “President Trump rightfully stepped in to restore law and order because of Gavin Newsom’s feckless leadership and his refusal to stop the violent attacks on American law enforcement.”

“It’s a bald-faced lie for Newsom to claim there was no problem in Los Angeles before President Trump got involved,” she added. “Everyone saw the chaos, violence, and lawlessness – unless, of course, Gavin Newsom doesn’t think any of that is a problem.”
