Police and elected officials say the troops and Marines sent by the Trump administration are not properly trained to interact with civilians. A judge will decide whether to limit their duties.

Actor John Leguizamo is among the celebrities who've commented on the protests, saying that "protesting is as American as apple pie."

Police arrested more than 20 people, mostly on curfew violations, on the first night of restrictions in downtown Los Angeles.

The National Guard has at times detained protesters in its deployment to Los Angeles, an official said Wednesday, as demonstrations against Immigration and Customs enforcement raids spread to other major cities.

Twenty-seven arrests were made at immigration protests in downtown L.A. on Sunday on suspicion of throwing a Molotov cocktail at an officer and driving a motorcycle into a line of police, authorities said.

The curfew went into effect in part of downtown Los Angeles amid ongoing protests over the Trump administration’s immigration crackdown.

Demonstrations against immigration raids began in Los Angeles last week and have spread across the country, including to Texas. More are planned this weekend.

The downtown curfew encircles the downtown civic center, including City Hall, the main county criminal courthouse, LAPD headquarters and federal buildings.
