President Donald Trump and his wife Melania met Republican Congressman Steve Scalise, who was critically injured in the shooting during a practice session for an annual baseball game in a Washington suburb.
Scalise was in critical condition after surgery, according to So Young Pak, spokeswoman for MedStar Washington Hospital Center. He has received multiple units of blood transfusion.
Trump says the wounded congressman, Republican Steve Scalise of Louisiana, is in stable condition.
The Trumps brought bouquets of flowers for the victims of the shooting during the visit that lasted less than half an hour, White House Press Secretary Sean Spicer told reporters. "My family and I will be forever grateful", said Williams becoming emotional.
Jackson rode in the motorcade, but had been to the hospital to confer on Scalise earlier, Spicer said.
James Hodgkinson, 66, of Belleville was shot by the U.S. Capitol Police who were on the scene during the Congressional practice.
Also shot were a congressional staffer and members of the Capitol police force.
FBI investigators said they are now examining the possibility that the motive for the shooting was political.
"We may have our differences but we do well in times like these", said Trump, speaking from the White House's Diplomatic Room.
Representative Bill Flores said a colleague who was at the practice told him the gunman asked if the baseball players were democrats or republicans. "Our thoughts and prayers are with the members of Congress, their staffs, Capitol Police, first responders, and all others affected", Trump said in a statement.
Trump praised Scalise as "a patriot" and "a fighter" and said Scalise has the prayers of the "entire nation" behind him.
He went on to say, "there's no doubt the heroism of the Capitol Police saved lives this morning, I am deeply thankful for their bravery, and I hope for speedy recoveries for all those wounded, in this cowardly assault".
Members of Vermont's congressional delegation reacted with shock and horror to learn that a gunman targeted members of the Republican congressional baseball team on Wednesday.
Griner remained in good condition in the hospital after being shot in the ankle, and Bailey was treated and released after sustaining a minor non-gunshot wound injury during the chaos.
