As President Donald Trump closed his remarks and invited first lady Melania Trump to the dais along U.S. 50 in downtown Washington, the assembled crowd of thousands began an impromptu rendition of "Happy Birthday."
The president, who turned 79 Saturday, smiled and paused as the singing gave way to a young Army officer approaching with a folded U.S. flag.
The officer presented Trump the flag on behalf of the U.S. Army Golden Knights and said it had flown over the Capitol earlier in the day to commemorate the nation’s oldest military branch.
