Five people, including the gunman, were shot Wednesday morning and two others suffered injuries, FBI Special Agent in Charge Timothy Slater said in an afternoon update.

Rep. Steve Scalise, congressional staffer Zack Barth, lobbyist Matt Mika and one Capitol Police officer were shot, Slater said. An additional Capitol Police officer was injured, and Rep. Roger Williams twisted his ankle while scrambling to the dugout when the gunfire broke out.
