Former U.S. Army prosecutor Glenn Kirschner said he believes what former President Donald Trump did on January 6, 2021, "qualifies as treason."Hundreds of Trump supporters violently stormed the U.S. Capitol a little over 15 months ago in an apparent effort to disrupt the formal certification of President Joe Biden's Electoral College victory in a joint session of Congress. Their attack came directly after Trump told them at a nearby Washington, D.C. rally to walk to the Capitol and "fight like hell" to save their country, following months of lying about the 2020 election results.
