The Marines’ arrival comes as a state challenge against Trump’s deployment of the National Guard continues in court.

The United States Marines have deployed to Los Angeles following criticism and legal battles over whether President Donald Trump had the authority to use the military to quell civilian protests without state approval.

On Friday, Major General Scott Sherman of the US Army confirmed that 200 Marines were arriving in southern California to protect a federal building. A total of 700 Marines have been authorised for deployment to the region.

“I would like to emphasise that the soldiers will not participate in law enforcement activities,” Sherman said during a briefing.

The Marines join National Guard troops already in the Los Angeles area following the eruption of protests on June 6, when residents took to the streets to express their displeasure with President Trump’s immigration raids, some of which targeted local hardware stores and other workplaces.
