The LAPD said on social media that the people in the crowd were throwing "rocks, bricks, bottles and other objects" while they were near the federal building.

The organized opposition was timed for the day President Trump is hosting a rare U.S. military parade in Washington that's taking place on his 79th birthday.

The largely peaceful protests during the "No Kings Day" demonstration in downtown Los Angeles took an intense turn in the afternoon. Police ordered the crowd to disperse at about 4:15 p.m. PDT near Alameda Street and Temple Avenue, according to the Los Angeles Police Department's Central Division.
