The video of John Spitzberg's arrest has been shared widely across social platforms, becoming a crystalizing moment for those protesting the Trump administration.
The U.S. Army celebrated its 250th anniversary on Saturday with a massive military parade in Washington, D.C., against a backdrop of political division and protests savaging President Trump.
The coalition of organizations behind the protests say the parade is being fueled by Trump's ego. The parade, which is not formally linked to Trump, will mark the 250th anniversary of the U.S. Army.
