WASHINGTON, June 14 (Xinhua) -- The gunman who opened fire Wednesday morning at a U.S. congressional baseball practice field has been identified as James T. Hodgkinson, a white male in his 60s.

Steve Scalise, a U.S. House Republican leader, was among the four wounded in the shooting as they were playing baseball game with other congressmen. The other three injured are two law enforcement officials and one aide to a House representative from Texas.

Hodgkinson, 66, owns a home inspection business, according to the authorities.

His home inspection license expired in November 2016 and was not renewed, a Washington Post report quoted Virginia state records as saying.

Hodgkinson was charged in April 2006 with battery and aiding damage to a motor vehicle, according to online records in St. Clair County, Illinois. The charges were dismissed, records show.

However, it's "too early to tell" if Republican members of congress were targeted by the gunman, FBI agent Tim Slater, who is in charge of the bureau's Washington field office, said at a press conference.

"Can you say yes, whether you think there is a political motivation in the shooting?" a reporter asked.

"No. Not aware of that. At all," Slater replied, "It's really early in the investigation."
