A top House Republican is among the five people wounded after a gunman opened fire on a Congressional baseball practice in Virginia Wednesday morning, leaving two people in critical condition.

Majority Whip Steve Scalise, 51, of Louisiana, and Zachary Barth, a legislative correspondent to Rep. Roger Williams (R-Texas), were among those transported to area hospitals from the Alexandria field, authorities said.

Matt Mika, a lobbyist for Tyson Chicken, and Capitol Police Officers Krystal Griner and David Bailey were also hospitalized following the shooting. Mika and Scalise were reported to be in critical condition.

An FBI press release Wednesday afternoon identified the shooter as James Hodgkinson, 66. Griner and Bailey reportedly exchanged gunfire with Hodgkinson, who was wounded and later died of his injuries.
