The gunman who carried out Wednesday's mass shooting outside Washington has been identified by multiple law enforcement sources as 66-year-old James T. Hodgkinson, a resident of Illinois. He allegedly used an M4 rifle in the attack on Republican congressmen practicing for a charity baseball game. Hodgkinson, who was shot and subdued by the congressmen's security detail, later died at a hospital. There has not been confirmation of any motive for the assault. Hodgkinson's Facebook page, which shows a banner image of Vermont Sen. Bernie Sanders, contains strong criticism of Republican congressmen and President Donald Trump. A message posted by Hodgkinson on March 22 says "Trump is a Traitor. Trump Has Destroyed Our Democracy. It’s Time to Destroy Trump & Co."
