Sen. Alex Padilla, D-Calif., has continued to defend himself and refute the claims by the Trump administration that he crashed Homeland Security Secretary Kristi Noem's news conference before federal officers shoved him outside the room, pushed him onto the floor and handcuffed him.

WASHINGTON (AP) — National Guard troops already have temporarily detained civilians in the Los Angeles protests over immigration raids, the commander in charge said Wednesday, but they quickly turned them over to law enforcement.

The detention of the U.S. Army veteran and immigrant who obtained U.S. citizenship, punctuated a series of unusual events that have appealed to Trump supporters but outraged other Americans.

The Marines and the National Guard personnel deployed amid the protests in to Los Angeles will operate under the same rules of force and will not be engaging crowds unless necessary, according to two U.S. officials.

U.S. Marines deployed to Los Angeles to help temper unrest in the city, stopped and detained an American citizen trying to enter a federal building.

Missouri has joined Texas in preemptively activating the state's National Guard ahead of the "No Kings" protests planned at about 2,000 sites across the nation on June 14 against President Donald Trump. Both Republican-led states followed Trump's lead after he tapped the California National Guard to respond to protests in Los Angeles.

President Donald Trump is thanking an appeals court for freezing an order that he return control of National Guard troops to California.

While the president contends that the L.A. protests against his immigration policy have been chaotic, the scenes are not as violent.
