U.S. President Donald Trump took the stage on Saturday to address the crowd attending the Army's 250th Birthday celebration, which featured a parade showcasing U.S. military equipment earlier in the day.

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.

Demonstrators crowded into streets, parks and plazas across the U.S. on Saturday to rally against President Donald Trump as officials urged calm and mobilized National Guard troops ahead of a military parade to mark the army's 250th anniversary,
