The American Civil Liberties Union said over 5 million people participated in protests against the Trump administration on June 14.

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 event was one of more than 2,000 “No Kings” rallies held across the country on Saturday, protesting what organizers call “authoritarianism, billionaire-first politics, and the militarization of our democracy.

Detectives believe the victim was at the demonstration as a bystander and “was not the intended target of the gunfire.”

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.
