Some attendees exited the military parade marking the 250th anniversary of the U.S. Army in Washington D.C. early, according to reports.

Thousands of Americans flocked to downtown D.C. in "Make America Great Again" hats and patriotic gear displaying Old Glory despite the balmy weather and thunderstorms brewing.

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.
