Crowd spontaneously sings ‘Happy Birthday’ at Army parade after Dems slam coincidental date.

The president spoke for an uncharacteristically short eight minutes, but in doing so delivered a stern warning to America’s enemies.

Trump Army parade’s speech

‘There is no earthly force more powerful than the brave heart of the U.S. military or an Army Ranger paratrooper or Green Beret,’ he told the crowd, sprawled far out onto the National Mall surrounding the Washington Monument.

There were fears ahead of Saturday’s event, which coincided with Trump’s 79th birthday, that the evening parade would have to be postponed or scrapped if there was lightning in the area.

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.
