US House Majority Whip, Republican, Steve Scalise, was shot Wednesday morning in Alexandria, Virginia, in what sources are calling an apparent "deliberate attack."
A congressional staffer and members of the congressional police force were also hit by yet to be identified gunman.
Scalise, the third ranking member of House Republican leadership as the majority whip, appeared to have been shot in the hip and it appeared two Capitol Hill police agents were shot, according to Rep. Mo Brooks, who told CNN he was on deck when the shooting occurred.
According to a statement from his office, as at 9:45 a.m. ET (1.45 p.m. GMT), Scalise was in stable condition but undergoing surgery.
"Prior to entering surgery, the whip was in good spirits and spoke to his wife by phone," the statement said. "He is grateful for the brave actions of U.S. Capitol Police, first responders and colleagues."
The shooting took place at a practice for the GOP congressional baseball team.
In a statement, Texas Rep. Roger Williams, one of the team's coaches, said one of his staff members was shot during the incident and is receiving medical attention. There was no information on the staffer's injuries.
According to both congressional and law enforcement sources, the shooting appears to be a "deliberate attack."
Two law enforcement sources told CNN the shooter, who is in police custody, has been taken to a hospital.
Members of Congress were practicing for a game that was scheduled for Thursday night at Nationals Park. It was not immediately clear whether it would go on as scheduled. The annual game has been played since 1909.
Lawmakers who spoke at the scene to reporters described a normal morning practice, at a field where they've practiced for years, when all of a sudden shots rang out. Lawmakers, staff members and even the young son of one of the members ran for cover, jumping into dugouts and over fences to avoid the gunshots.
