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

House Speaker Mike Johnson would not weigh in on whether California Gov. Gavin Newsom should be arrested -- a suggestion made by President Donald Trump -- but said the governor should be "tarred and feathered."

"Look, that's not my lane. I'm not going to give you legal analysis on whether Gavin Newsom should be arrested, but he ought to be tarred and feathered. I’ll say that," Johnson said Tuesday at the weekly GOP news conference. "He's standing in the way of the administration and the carrying out of federal law, right? He is applauding the bad guys and standing in the way of the good guys."

"Do your job, man. That's what I tell Gavin Newsom," Johnson added. "Stop working on your rebranding and be a governor. Stand up for the rule of law."

Newsom clapped back on social media, writing, "Good to know we’re skipping the arrest and going straight for the 1700’s style forms of punishment. A fitting threat given the @GOP want to bring our country back to the 18th Century."

Johnson said Trump's actions sending Marines and National Guardsmen to LA is "full in his authority" to "maintain order."

"President Trump has put his hand on the table and said, 'Not on my watch,' and we applaud that, so we’re standing with him," he said.

"We've got to protect them [federal law enforcement], and federal employees, as well, and federal buildings and property," Johnson said. "We're not going to let violent criminals destroy the property of U.S. taxpayers."

Speaker Emerita Nancy Pelosi on Tuesday blasted Trump sending the National Guardsmen to LA, noting how she urged Trump to send in the guard during the Jan. 6, 2021, insurrection at the Capitol -- when rioters attacked law enforcement and destroyed property -- but the president refused to do so.

Bryn MacDonnell, the special assistant to the secretary of defense who serves as the agency's comptroller, testified before the House Appropriations Subcommittee on Defense that the costs for deploying the Marines and National Guard to Los Angeles was an estimated $134 million. "Which is largely just [temporary duty] cost: travel, housing, food, etc.," she explained.

When asked by Rep. Pete Aguilar, D-Calif., for more details and where the money was coming from, MacDonnel said, "their own accounts."br/>

Gen. Eric Smith, the commandant of the Marine Corps, told the Senate Armed Services Committee that the 700 Marines being sent to Los Angeles received crowd control training in Twentynine Palms, California.

Sen. Richard Blumenthal, D-Conn., expressed his doubts about the use of combat-trained units domestically, saying he was "deeply worried" that their deployment increased the risk of lethal force possibly being used.

Smith said he’s not concerned, adding, "I have great faith in my Marines."

Smith said the Marines -- who are equipped with shields and batons -- do not have arrest authority but will be providing support to law enforcement protecting federal property and personnel.

Sen. Elissa Slotkin, D-Mich., asked Smith if he knew how much crowd control training Marines receive. Smith said he didn't have the precise number but said it was "in excess of two hours," calling it "a standard annual training in the use of non-lethal means."

Slotkin noted that the police forces on the street receive 600 hours of crowd control training.

During Defense Secretary Pete Hegseth’s testimony on Capitol Hill, Rep. Betty McCollum, the top Democrat on the House Appropriations Defense Subcommittee, asked the cost of sending Marines and the National Guard to Los Angeles and what resources were being taken away by the move, but Hegseth repeatedly did not answer the question.

Hegseth said ICE “has the right to safely conduct operations in any state and any jurisdiction in the country," and drew comparisons to the 2020 George Floyd protests.

"ICE ought be able to do its job, whether it's Minneapolis or Los Angeles," he said.

"We have deployed National Guard and the Marines to protect [ICE] in the execution of their duties, because we ought be able to enforce integration immigration law in this country," he said.

McCollum insisted the Marines aren’t trained for a domestic mission but Hegseth insisted they were.
