The U.S. Northern Command is responding to photos published in the San Francisco Chronicle showing National Guardsmen sleeping on floors.

"The soldiers in the photo were resting as they were not currently on mission and due to the fluid security situation, it was deemed too dangerous for them to travel to better accommodations," a U.S. Northern Command spokesperson said.

LA Mayor Karen Bass noted Tuesday that "the unrest that has happened are a few blocks within the downtown area -- it is not all of downtown and it is not all of the city."

"The Soldiers have ready access to food and water as needed," the spokesperson added.

California Gov. Gavin Newsom had posted the photos on social media Monday to raise concerns about their care and housing.

Newsom said they were deployed "without fuel, food, water or a place to sleep," adding that President Donald Trump "is treating our troops disrespectfully."

On Monday night, 14 people were arrested for looting and 96 people were arrested for failure to disperse in downtown LA, the LAPD said.

There was also one arrest for assault with a deadly weapon, one arrest for resisting arrest and one arrest for vandalism, police said.

"Numerous less-lethal rounds" were used by the LAPD to control the crowd, police said.

Two LAPD officers were hurt; they were treated at a hospital and later released, police said.

Los Angeles Mayor Karen Bass said Tuesday that she and the LAPD are considering curfews and other responses in case violence breaks out again.

There was some looting Monday night, but the protests were much smaller and less violent than over the weekend, she said. There's a possibility of one rally on Tuesday, she said.

Bass said the vandalism and violence aren’t acceptable, adding that she feels those individuals aren’t in support of immigrants and "have another agenda."

She noted that "the unrest that has happened are a few blocks within the downtown area -- it is not all of downtown and it is not all of the city."

The mayor argued the National Guard is not stopping the violence because their one job is to guard the federal building downtown and a federal building in Westwood. Asked what the Marines will do in LA, she responded, "I have no idea."

Bass also stressed that the protests stem from Friday’s raids, which she said left immigrant families across LA "terrified" and unsure if they should go to school or work.

She urged ICE to stop the raids. LA is a city of immigrants, Bass said, and she cited the raids' "disruption" to families and the local economy.

While most House Republicans are standing behind President Donald Trump’s decision to deploy Marines and the National Guard to Los Angeles, one moderate Republican, Rep. David Valadao of California, issued a rare criticism of the administration’s operation.

"I remain concerned about ongoing ICE operations throughout CA and will continue my conversations with the administration -- urging them to prioritize the removal of known criminals over the hardworking people who have lived peacefully in the Valley for years," Valadao, who represents an agriculture-heavy district in Central California, wrote on social media.

He said while he supports the right to peacefully protest, "the violence and vandalism happening in Los Angeles is unacceptable and I stand with our law enforcement officers working to protect people and regain control over the situation."
