Republican and Democratic team members set aside partisan politics Thursday night to play the game, and said they are competing as one - Team Scalise.
James Hodgkinson is the Belleville man who shot a congressman and three others Wednesday during practice for the baseball game.
"It's been much more hard than people even thought at the time", Mr Trump said of the treatment of Mr Scalise, the No 3 GOP leader, who is in critical condition and underwent a third surgery at the MedStar Washington Hospital Centre.
Game organizers say more than 20,000 tickets have been sold, and more than $1 million has been raised for Congressional Sports for Charity.
A Democrat ally of Steve Scalise asked for better protection for himself and his fellow lawmakers a week before the House of Representatives Majority Whip was left fighting for his life after Wednesday's shooting at a Congressional baseball practice.
"It's been much more hard than people even thought at the time", Trump told reporters at the White House on Thursday, adding that he also had visited a wounded Capitol Police officer at the hospital.
Instead of wearing hats representing their home teams, as is the normal tradition, players on both teams wore Louisiana State University hats in honor of Scalise, a Louisiana Republican, for part of the game.
The two team managers, Republican Representative Joe Barton and Democratic Representative Mike Doyle, both vowed that their squads would win the charity game.

However, a congressional aide-turned-lobbyist, Matt Mika, was shot multiple times and critically injured, and he remained in hospital.
Trump and First Lady Melania visited Scalise's family - as well as that of wounded officer Crystal Griner, who is also at MedStar Hospital- last night. "The game will go on". It is a rare and genuine opportunity for Democrats and Republicans to put their divisions aside and show those gathered in the stadium and watching across the U.S., that they are not just politicians - they are people and players.
Republicans and Democrats prayed together on the field before the game.
"Especially after the men's game made a decision to persevere. everyone wanted to move forward", said Congressional Women's Softball Game President Atalie Ebersole.
But Flake said the final score wasn't likely to matter this year.
Investigators said Thursday that weapons recovered at the Alexandria scene were purchased legally and that they are examining electronics recovered from the suspect's vehicle, including his cell phone, computer and camera.
"I'll miss the banter with him back and forth", Richmond said of the heckling they usually exchange from opposing dugouts.
