The president celebrates the 250th anniversary of the US Army as demonstrators hold "No Kings" events from coast to coast.

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.

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.

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