The LAPD said on social media that the people in the crowd were throwing "rocks, bricks, bottles and other objects" while they were near the federal building.

Social media users slammed CBS News for seemingly advertising "No Kings Day" protest merchandise ahead of anti-Trump demonstrations, calling the move unethical amid controversies.

Coordinated "No Kings" protests are happening from coast to coast, part of a "national day of peaceful protest" against the Trump administration, expected to draw millions. Protesters in some areas braved wet weather to raise signs and chant slogans supporting the rights of immigrants and criticizing what they see as Trump's power grab.

The "No Kings" protest and march happening in Philadelphia on Saturday coincides with hundreds of rallies scheduled to take place across the country.
