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.

Thousands turned out to enjoy festivities and a sprawling military parade in Washington, D.C., even as dismal weather forecasts and nationwide anti-Trump “No Kings” protests threatened to dampen the Army’s 250th birthday celebration.

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.

Army's 250th anniversary celebrated with a military parade in Washington, D.C., on Trump's birthday. 'No Kings' protests by opponents are planned across the country.

The parade, which was put on to celebrate the Army’s 250th anniversary and Trump’s 79th birthday, was reported to cost up to $45 million and drew thinner crowds than anticipated, as simultaneous “No Kings” protests took place in all 50 states.

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.

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.

The parade must go on, and the Army sidestepped a major crisis of image and messaging. The Army’s 250th birthday parade was not the grand military spectacle that many anticipated, and for that Americans can breathe a momentary, measured sigh of relief.

Pa., has voiced support for President Donald Trump’s military parade, saying Americans should support it regardless of politics. "This parade is comprised of our sons, daughters, mothers and fathers — the very best of us.

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.

Sen. Rand Paul criticized the June 14 military parade, arguing that it was too expensive and “glorified” weapons.
