NBC News' Jacob Soboroff reports from Los Angeles City Hall where thousands of protesters have gathered for a 'No Kings' protest against the Trump administration and ahead of the president's Washington D.

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.

President Trump has called for expanded deportation operations in Los Angeles after "No King Day" protests over the weekend and anti-ICE protests last week in response to ICE raids across Southern California.

Los Angeles Mayor Karen Bass announced that the nightly curfew will be extended for a few more days amid ongoing protests against immigration raids.

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.

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