The president celebrates the 250th anniversary of the US Army as demonstrators hold "No Kings" events from coast to coast.

On his 79th birthday, President Trump spent more than three hours on Saturday taking in the scene at a military parade commemorating the 250th anniversary of the U.S. Army.

The 250th anniversary of the United States Army could see hundreds of thousands descend on Washington DC to watch tanks roll through the streets for the first time in three decades.
