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.

Follow live updates as the military parade in Washington, D.C., kicks off on Trump's birthday. 'No Kings' protests by opponents are planned across the country today.

Car horns, chants and cheers filled the air around the Williamsburg-James City Courthouse on Saturday night as thousands of people participated in the largest “No Kings” rally in the region.

Across the country, relatively few disruptions were reported during protests and marches where the mood ranged from joyful to defiant.

Atlanta’s 5,000-capacity “No Kings” rally quickly reached its limit, with thousands more demonstrators gathered outside barriers to hear speakers in front of the state Capitol. Huge crowds marched in New York, Denver, Chicago, Houston and Los Angeles, some behind “no kings” banners.

The parade, honoring the Army’s long-planned 250th anniversary celebration and coinciding with Trump’s 79th birthday, is set to step off from the Lincoln Memorial under the threat of stormy weather in Washington and protests around the country tied to a turbulent week of immigration enforcement that has involved military deployment in Los Angeles.

The parade was the spectacle event Trump had long wanted. It also helped sparked the largest mass opposition to him since his inauguration 145 days earlier.

“The most threatening sound to an oligarch is laughter.”

The rally at Daley Plaza started at noon with a moment of silence for the shootings in Minnesota before moving into the streets of downtown Chicago.

As part of nationwide protests against Trump administration policies, Texans hit the streets in at least sixty cities.
