Newsom's 2028 presidential aspirations hang in the balance as the eyes of the nation are on California's clash with immigration authorities.

After the Trump administration sent Marines and National Guard troops to Los Angeles in response to the protests against immigration enforcement, Gov. Ron DeSantis proposed adding another group to the mix: the Florida State Guard.

A judge denied Newsom’s request to limit President Donald Trump’s use of California National Guard troops in Los Angeles.

Another 2,000 National Guard troops along with 700 Marines are headed to Los Angeles on orders Monday from President Donald Trump, escalating a military presence local officials and Gov. Gavin Newsom don’t want and the police chief says creates logistical challenges for safely handling protests.

It's been five days since anti-ICE demonstrations erupted in Los Angeles, some turning violent between protesters and law enforcement officers, prompting President Trump to deploy National Guard troops and hundreds of Marines.

4:47 p.m. EDT The Trump administration asked the judge to reject Newsom’s request and allow it to respond by Wednesday, calling Newsom’s attempt to block the deployment of federal troops “legally meritless” and saying it would jeopardize the safety of Homeland Security personnel and interfere with the government’s ability to carry out operations.

U.S. District Judge Charles Breyer, a former Watergate prosecutor, will decide whether Trump had the legal authority to federalize 4,000 California National Guard troops.

Dozens arrested in Los Angeles as anti-ICE protests turn violent, with charges including assault on police and attempted murder as National Guard troops deploy.
