California officials are filing a lawsuit Monday against President Donald Trump in response to the administration’s extraordinary deployment of the National Guard to confront immigration protesters who took to the streets in Los Angeles.

Attorney General Rob Bonta said the deployment “trampled” the state's sovereignty. He planned to seek a court order declaring that Trump’s use of the Guard was unlawful and ask for a restraining order to halt the deployment.

The streets of the sprawling city of 4 million people were quiet Monday morning, but the smell of smoke hung in the air downtown, one day after crowds blocked off a major freeway and set self-driving cars on fire as police responded with tear gas, rubber bullets and flash-bang grenades. The law enforcement presence was heavy, with police cars blocking the street in front of the federal detention facility that was a focus of the protests.

While much of the city was spared from any violence, clashes swept through several downtown blocks and a handful of other places. It could take days to clear the debris from burned cars and to clean off or paint over graffiti sprayed on City Hall and other buildings near the detention facility. Sunday was the third and most intense day of demonstrations against Trump’s immigration crackdown in the region, as the arrival of around 300 Guard troops spurred anger and fear among many residents.

U.S. officials said about 1,000 National Guard members were in the city under federal orders by midday Monday. The full 2,000 members authorized by the president were expected to be on the ground by the end of the day. The officials spoke on condition of anonymity to discuss the details of military operations.

Many protesters dispersed as evening fell and police declared an unlawful assembly, a precursor to officers moving in and arresting those who refuse to leave. Some of those who stayed threw objects at police from behind a makeshift barrier. Others hurled chunks of concrete, rocks, electric scooters and fireworks at California Highway Patrol officers and their vehicles parked on the closed southbound 101 Freeway. Officers ran under an overpass to take cover at one point.

Trump said Monday that the city would have been “completely obliterated” if he had not deployed the Guard.

Writing on his social media platform, Truth Social, the president accused Newsom and the city's mayor, Karen Bass, of lying by saying Guard troops were not necessary.

The Guard was deployed specifically to protect federal buildings, including the downtown detention center where protesters concentrated.

Trump also signaled he would support the arrest of California Gov. Gavin Newsom over his handling of immigration protests in Los Angeles that flared over the weekend.

Los Angeles Police Chief Jim McDonnell said officers were “overwhelmed” by the remaining protesters. He said they included regular agitators who show up at demonstrations to cause trouble.

Several dozen people were arrested throughout the weekend. One was detained Sunday for throwing a Molotov cocktail at police and another for ramming a motorcycle into a line of officers.

Trump responded to McDonnell on Truth Social, telling him to arrest protesters in face masks.

“Looking really bad in L.A. BRING IN THE TROOPS!!!” he wrote.
