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

House Speaker Mike Johnson said he is “not concerned at all” over President Donald Trump's order to send 2,000 National Guard troops to respond to immigration protests in Los Angeles.

“I think the president did exactly what he needed to do,” Johnson told ABC News' "This Week" co-anchor Jonathan Karl on Sunday. “That is real leadership and he has the authority and the responsibility to do it.”

Secretary of Defense Pete Hegseth said he is prepared to mobilize Marines if the violence continues. Pressed if sending Marines into the streets of American cities is warranted, Johnson said, “We have to be prepared to do what is necessary.”

Multiple people were detained after reentering an area the Los Angeles Police Department had ordered them to leave, the department said.

"Those detained will be arrested and booked for failing to disperse from an area where an unlawful assembly was ordered," the department’s Central Division said in a statement posted on social media at midnight.

An order to disperse had been issued about three hours prior.

The division said "multiple" people were detained on Alameda Street between Aliso and Temple streets, which are near the local office of the U.S. Justice Department, on the eastern side of Downtown Los Angeles.

Police officials didn’t say how many people had been taken into custody.

LA Mayor Karen Bass, who condemned the Trump administration's immigration enforcement actions on Friday as stoking fear, called reports of unrest Saturday outside the city limits disturbing.

"This is a difficult time for our city," Bass said in a statement on X. "As we recover from an unprecedented natural disaster, many in our community are feeling fear following recent federal immigration enforcement actions across Los Angeles County. Reports of unrest outside the city, including in Paramount, are deeply concerning. We’ve been in direct contact with officials in Washington, D.C., and are working closely with law enforcement to find the best path forward. Everyone has the right to peacefully protest, but let me be clear: violence and destruction are unacceptable, and those responsible will be held accountable."
