A 33-mile trip from one protest in Annapolis, Md., to the parade grandstand in front of the White House was like a journey between two different countries.

Washington, D.C., played host to a grand military parade celebrating the U.S. Army’s 250th birthday—a ceremony that coincided with President Donald Trump’s 79th birthday and Flag Day. The event unfolded along Constitution Avenue from the Lincoln Memorial to the Washington Monument and closed with a fireworks show over the Tidal Basin.
