A top US Republican was among five people wounded in a "multiple shooting" during baseball practice in an upmarket Washington DC suburb.
House of Representatives Majority Whip Steve Scalise was hit but expected to survive after the early morning attack at a park in Alexandria, Virginia.
Two police officers who engaged in a shootout with the attacker were reportedly among the wounded.
Police said the gunman was among five people taken to hospital.
Alexandria police tweeted: "Suspect is in custody and not a threat."
The lawmakers were practising for the annual congressional ballgame scheduled to be played on Thursday at Nationals Park, home of Major League Baseball team the Washington Nationals.
