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

President Donald Trump posted on Truth Social on Sunday, instructing his administration -- specifically Secretary of Homeland Security Kristi Noem, Secretary of Defense Pete Hegseth and Attorney General Pam Bondi -- to take all necessary actions to "liberate Los Angeles from the migrant invasion."

Trump claimed that "violent insurrectionist mobs" are attacking federal agents to halt his administration's deportation efforts.

"Order will be restored, the Illegals will be expelled, and Los Angeles will be set free," Trump wrote.

On Saturday, Trump signed a memorandum to deploy the National Guard as protests in Los Angeles entered their third consecutive day. The memorandum stated that up to 2,000 service members could be deployed for a duration of 60 days or as determined by the defense secretary. The National Guard arrived in Los Angeles overnight.

Both the president and the secretary of defense have not ruled out sending Marines to California.

President Donald Trump, accompanied by Secretary of State Marco Rubio, spoke to reporters on the tarmac on Sunday before departing for Camp David.

As protests over immigration enforcement operations continue in Los Angeles, the president did not rule out sending active-duty Marines to California, confirming Secretary of Defense Pete Hegseth's earlier suggestion.

Trump's comments come as California National Guard troops arrived in Los Angeles on Sunday, a decision that drew ire from Democratic governors, including California's Gov. Gavin Newsom.

When asked what the bar is to send Marines, Trump said the bar is "what I think it is."

"The bar is what I think it is. If we see danger to our country and to our citizens, and we'll be very, very strong in terms of law and order," Trump said.

Trump also claimed that protestors are spitting at police officers and suggested a new saying he's created: "they spit, we hit."

"They spit, we hit," Trump said. "I told them, nobody's gonna spit on our police officers, nobody's gonna spit on our military, which they do, it is a common thing. They get up to them and go this far away, and then they start spitting in their face. If that happens, they get hit very hard."

In a joint statement released Sunday through the Democratic Governors Association, 22 Democratic governors called President Donald Trump's deployment of the National Guard in California in response to protests over immigration enforcement operations "an alarming abuse of power."

"It’s important we respect the executive authority of our country’s governors to manage their National Guards — and we stand with Governor Newsom who has made it clear that violence is unacceptable and that local authorities should be able to do their jobs without the chaos of this federal interference and intimidation," the statement reads, in part.

President Claudia Sheinbaum of Mexico said on Sunday that 35 Mexican citizens were arrested in Los Angeles raids conducted by U.S. Immigration and Customs Enforcement on Friday.

The ICE raids set off violent protests and clashes between demonstrators and immigration officers, officials said.

Sheinbaum said Mexican authorities, including staff from the Mexican Consulate in Los Angeles, are in touch with those arrested.

"Mexicans living in the United States are good men and women," Sheinbaum said. "These are men who left for the United States to seek a better life for themselves and their families. They are not criminals. They are good men and women."
