Steve Scalise, the third highest-ranking Republican in the House of Representatives, was among five people taken to hospital after a shooting at a baseball practice in Alexandria, Va., involving Republican politicians and officials.
Scalise's office released a statement indicating he was shot in the hip and underwent surgery.
"Prior to entering surgery, [Scalise] was in good spirits and spoke to his wife by phone. He is grateful for the brave actions of U.S. Capitol Police, first responders, and colleagues," the statement read.
The FBI is overseeing the investigation, as it involves crimes against federal officials, but officials were tight-lipped at a news conference.
Tim Slater of the FBI said it was too early to tell if anyone was targeted or if it was a random act.
