ABC News(ALEXANDRIA, Va.) — At least 20 Republican members of Congress were in attendance at Wednesday morning’s baseball practice in Alexandria, Virginia, when a gunman began firing, injuring House Majority Whip Steve Scalise, R-La., and at least four other people.

The GOP lawmakers that make up a 34-member team had been practicing for Thursday’s annual charity congressional baseball game.

Zach Barth, a staffer of Rep. Roger Williams, was also injured. Barth is “receiving medical attention, but is doing well and is expected to make a full recovery,” according to Williams.

Also among the injured is Matt Mika, the director of government relations for Tyson Foods’ Washington, D.C., office.

“He has been taken to a local hospital and we’re awaiting word on his condition. Matt has worked for Tyson Foods for more than six years and we’re deeply concerned about him and his family,” a spokesperson for Tyson Foods said in a statement.

Rep. Brad Wenstrup of Ohio treated Scalise immediately after he was shot. Wenstrup has a medical degree and served in Iraq as a combat surgeon.

“I felt I was back in Iraq, but without my weapon,” Wenstrup told Fox News.

Here is the full list of attendees at the routine early-morning baseball practice that turned into a terrifying, chaotic scene:
