Who was present during the GOP congressional baseball team practice shooting in Virginia
The FBI said it's too early to determine if congressmen were targeted.
— -- At least 20 Republican members of Congress were at this 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 who make up the 34-member team were practicing for Thursday's annual charity congressional baseball game.
Zach Barth, a staffer for 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 Tyson spokesperson 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.
