Former Secretary of State Hillary Clinton took aim at one of President Donald Trump’s greatest insecurities on Sunday, needling him over the lackluster crowd at his Washington, D.C. military parade this past weekend.

Law enforcement officials reported no arrests from the celebration in D.C. that drew several thousand parade watchers, with some demonstrators protesting against the show of military strength.

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.

President Donald Trump praised the United States Army as the “greatest, fiercest and bravest fighting force” at the conclusion of a grand display of military might in the nation’s capital Saturday as the Army celebrated its 250th birthday with a parade.

Donald Trump will be keeping a close eye on the U.S. Open on Sunday, as he looks to put an embarrassing military parade behind him.

The procession, with more than 6,000 soldiers and 128 Army tanks, was one Trump tried to make happen in his first term.

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.
