Coinciding with Trump's 79th birthday, the parade will feature tanks, bands and thousands of troops in honor of the Army’s 250th anniversary celebration.

WSJ's senior political correspondent Molly Ball reports from the parade route, where vintage tanks and other military hardware are rolling down Constitution Avenue in Washington.

Thousands of demonstrators crowded into streets, parks, and plazas across the US, blaring anti-authoritarian chants mixed with support for protecting democracy and immigrant rights.

President Trump is hosting a parade celebrating the 250th anniversary of the U.S. Army on Saturday, bringing tanks and soldiers to the streets of Washington, D.C., for the capital's first major military parade in more than three decades.

The day-long celebration of the Army’s 250th birthday coincided with nationwide protests against Trump and military strikes between Israel and Iran that are testing the president’s “America First” resolve.
