Thousands of demonstrators crowded into streets, parks, and plazas across the US, blaring anti-authoritarian chants mixed with support for protecting democracy and immigrant rights.

The president celebrates the 250th anniversary of the US Army as demonstrators hold "No Kings" events from coast to coast.

Palantir, the data analysis and technology firm whose contracts with the federal government are expanding, and Coinbase, a cryptocurrency firm that donated to the president’s inauguration, also sponsored the event. Oracle, a database company whose co-founder is a close friend of Mr. Trump’s, received a shout-out on Saturday as a sponsor.

More than 6,000 soldiers participated in the U.S. Army's 250th anniversary parade in Washington, D.C. — including the Texas A&M University Corps of Cadets.

Fox News Digital spoke to attendees of the D.C. military parade, some who had traveled hundreds of miles to participate, about why they had come to the nation’s capital for the event.

Vice President Vance spoke at the Army’s 250th anniversary parade, saying how proud he is of U.S. soldiers. He also wished President Trump a happy birthday and nodded to his wife on their wedding anniversary.

The parade is telling the story of the U.S. Army’s history, beginning with the Revolutionary War. Soldiers are marching in historic uniforms, with military assets from each major conflict represented.
