The procession featured more than 6,000 soldiers, 128 Army tanks, aircraft flyovers, military bands, even robot dogs. Troops wore uniforms representing the Army’s history, including outfits from the Revolutionary War, Civil War, World War II, the Vietnam War and the Global War on Terror.

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

Meanwhile, "No Kings" protests were scheduled in all 50 states to counter Trump's celebration, in cities like New York, Los Angeles, Philadelphia and Boise.

Donald Trump wanted a military parade, and Saturday he got it. Trump seemed pretty pleased by it all, but some folks on social media are convinced that the president dozed off, at least for a few seconds, during the festivities. It’s not just talk.

Thousands of Americans flocked to downtown D.C. in "Make America Great Again" hats and patriotic gear displaying Old Glory despite the balmy weather and thunderstorms brewing.

“Earlier today, during a parade held in support of our nation’s military and organized by President Donald Trump, the song ‘Barracuda’ by Heart was played without permission or authorization from us,“ Wilson said in a post on Instagram late Saturday night.

MSNBC host Chris Hayes couldn’t contain his laughter on air Friday while reading a fundraising email from President Donald Trump. The email asked for donations for his Saturday military parade, which, as it turns out, most Americans aren’t that eager to fund.

The military parade to mark the Army’s 250th anniversary and its convergence with President Donald Trump’s 79th birthday are combining to create a peacetime outlier in U.S. history. Yet it still reflects global traditions that serve a range of political and cultural purposes.
