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.

Details on the "No Kings" protests scheduled Saturday across Los Angeles, including locations, times, and how to find “No Kings protest near me" and “No Kings protest locations."

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.

More than 1,500 events are planned throughout the U.S. to send a loud message to President Donald Trump: “In America, we don’t do kings.”

Protesters across Southern California and the country took to the streets for ‘No Kings’ demonstrations against President Trump and the $45-million celebration of the U.S. Army’s 250th birthday, which coincides with Trump’s 79th.

"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.
