The Capitol Police officer who helped to take down a gunman threw out the first pitch at the Congressional Baseball Game at National Park on Thursday.

The game took place one day after a gunman opened fire on Republican lawmakers practicing at a field in Alexandria, Va. Four people were shot, and Officer David Bailey, who took the mound Thursday evening still in crutches, was injured during the incident.

Also, before the game, Republicans and Democrats huddled together and knelt for a prayer for the victims of the shooting.

Sen. Rand Paul, R-Ky., said that the shooting would have been a "massacre" without the actions of the Capitol Police.

"Had they not been there, it would have been a massacre, because there's no escaping a guy you know if he's got several hundred bullets, and we had no weapons and no place to hide," Paul said. "So if he would have advanced on the rest of us, there would have been no chance, the only chance we had was that the shots were returned by the Capitol Hill police."

Crystal Griner, the other Capitol Police officer who helped take down the gunman, remains in the hospital after she was shot. Among the others wounded are Tyson lobbyist Matt Mika and House Majority Whip Steve Scalise, who is in critical condition.
