The grand military parade that President Donald Trump had been wanting for years barrelled down Constitution Avenue on Saturday with tanks, troops and a 21-gun salute, playing out against the counterpoint of protests across the country by those who decried the U.

The procession, with more than 6,000 soldiers and 128 Army tanks, was one Trump tried to make happen in his first term.
