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.

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.

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.

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.

As millions of Americans protested at “No Kings” rallies across the country, onlookers gathered in Washington on the president’s birthday for a muted celebration.
