U.S. Marines have temporarily detained a man after he walked onto the property of a federal building they were guarding in Los Angeles.

In an exclusive interview with Meet the Press, Sen. Adam Schiff (D-Calif.) condemns President Trump’s call to send the National Guard and Marines into Los Angeles amid protests and criticizes the forceful removal of fellow California Sen.

President Donald Trump has deployed 4,000 National Guardsmen and 700 Marines to LA. But California Gov. Gavin Newsom and California Attorney General Rob Bonta are suing the Trump administration, saying they unlawfully "trampled over" California’s sovereignty when they federalized the California National Guard.

By Omar Younis, Brad Brooks, Phil Stewart and Idrees Ali LOS ANGELES (Reuters) -U.S. Marines deployed to Los Angeles made their first detention of a civilian on Friday, part of a rare use of military force to support domestic police and coming ahead of national protests over President Donald Trump's military parade in Washington.

Around 200 Marines armed with rifles, riot control equipment, gas masks, roughly 20 hours of civil disturbance training and the ability to temporarily detain civilians arrived in the country's second-largest city after days of public anticipation.

The Marines will defend federal property and personnel, rather than operating law enforcement operations, according to an Army general.

About 50 U.S. Marines squared off against hundreds of protesters in front of a federal building in downtown Los Angeles on Saturday, with the crowd yelling in unison for them to go home.

Marines deployed to Los Angeles temporarily detained a civilian on Friday, the U.S. military confirmed after being presented with Reuters images.

Many Mexican Americans remember that California became part of the United States after a 19th century war that cost Mexico more than half its territory.
