Elon Musk posted a cryptic message about the "No Kings" protests after activists took to the streets across the U.S. over the weekend.

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.

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.

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.

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