Live updates: 700 Marines deployed to help National Guard in LA protests

President Donald Trump has authorized the deployment of an additional 2,000 National Guard members to respond to immigration protests in Los Angeles, according to U.S. officials.

The order would put them on active duty. One official warned, however, that the order was just signed and it could take a day or two to get troops moving. The officials spoke on condition of anonymity to discuss troop movements.

The news comes hours after the Pentagon deployed about 700 Marines to the protests to work alongside local law enforcement.

What to know:

• LAPD chief’s concerns: Los Angeles Police Chief Jim McDonnell says the department has not been given any “formal notification” that the Marines will be coming to the city, and that their arrival, without coordinating with the police department, would present “a significant logistical and operational challenge.”
• California’s lawsuit: The state sued Trump over his use of the Guard troops as growing numbers of demonstrators took to the city’s streets for a fourth day. California Attorney General Rob Bonta announced the lawsuit by telling reporters that Trump had “trampled” the state’s sovereignty.
• Trump threatens to arrest Newsom: “I would do it if I were Tom. I think it’s great,” Trump said, referencing Tom Homan, the administration’s border czar, who warned that anyone, including public officials, would be arrested if they obstructed federal immigration enforcement. “Come after me, arrest me. Let’s just get it over with, tough guy,” Newsom said.
