According to Jinse Finance, this is the largest military parade in Washington in decades. Today, dozens of tanks and armored vehicles rolled through the streets of the U.S. capital to celebrate the 250th anniversary of the founding of the U.S. Army. Nearly 7,000 soldiers are participating in the event, which also coincides with U.S. President Trump's 79th birthday. Trump was warmly received at the parade and an impromptu birthday celebration was held. As he arrived, a 21-gun salute was fired and the crowd began singing "Happy Birthday" to Trump. Meanwhile, protests against Trump broke out across the United States. In Washington, D.C., a march headed toward the White House. The organizing group stated that 1,000 people took part, with some holding signs reading "Trump must step down immediately." In Los Angeles, police attempted to disperse protesters at a "No Kings" demonstration using smoke or gas.
