In Los Angeles, 38 people were arrested downtown on Saturday night, police said Sunday. In Huntington Beach, police arrested a convicted felon they said had a loaded handgun.

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.

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.

"I think we will see the largest peaceful single day protests that this country has seen certainly since the first Trump term," said Indivisible cofounder Ezra Levin, one of the organizers.
