WATCH: Trump applauds U.S. Army’s ‘legacy of unmatched courage’ at 250th anniversary parade in D.C.

The 250th Anniversary of the U.S. Army parade concluded with a fireworks display in Washington, D.C. on Saturday evening.

The event coincided with President Trump's 79th birthday and Flag Day.

Trump delivered an address at the event, where he lauded the U.S. Army’s "legacy of unmatched courage" and sacrifice. 

“There is no earthly force more powerful than the brave heart of the U.S. military or an Army Ranger paratrooper, or Green Beret,” Trump said. “They are the best. They are the finest from Bunker Hill to San Juan Hill, from Gettysburg to Guadalcanal, from Yorktown to Shiloh, and from the trenches of the Argonne to the mountains of Afghanistan, the Army has forged a legacy of unmatched courage, untold sacrifice.”

Anti-Trump "No Kings" protests in cities and towns across the country were taking place as the 250th anniversary celebration unfolded.
