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.

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.

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.

Tanks and thousands of troops will soon take to Washington, D.C., streets for the Army's 250th anniversary on President Donald Trump's birthday.
