A Louisiana congressman is among the victims of a shooting during a Wednesday morning baseball practice in Alexandria, Virginia, according to multiple reports.
CNN is reporting that House Majority Whip Steve Scalise, R-Louisiana, and two Capitol police officers were wounded in the shooting.
U.S. Rep. Mo Brooks, R-Alabama, who witnessed the shooting, said at least 50 shots were fired.
Brooks said he took off his belt and applied a tourniquet to try to slow down the bleeding.
The extent of victims' injuries was not immediately known, but a source told ABC News that the Scalise's injury was not life-threatening.
Alexandria police say the suspect is in custody and not a threat.
Four Florida congressmen -- Ron Desantis, Matt Gaetz, Dennis Ross and Tom Rooney -- were on the Republican congressional baseball team roster.
"The vice president and I are aware of the shooting incident in Virginia and are monitoring developments closely," President Donald Trump said in a statement. "We are deeply saddened by this tragedy. Our thoughts and prayers are with the members of Congress, their staffs, Capitol police, first responders and all others affected."
ABC is reporting that the FBI has arrived at the scene.
