Mr Trump in a video message that was aired before the Congressional Baseball Game yesterday, thanked members, staff and the crowd for supporting the event.
"As you all know, tonight's game has taken on a much deeper level of meaning. Beyond anything that we would have thought. By playing tonight, you are showing the world that we will not be intimidated by threats, acts of violence, or assaults on our democracy. The game will go on," Mr Trump said.
"I want to take a moment to send our thoughts, love, and prayers to Congressman Steve Scalise and his entire family," he said.
Indian-American Congressman Ami Bera who attended the game said that the congressional baseball game is a bipartisan American tradition.
"Both parties put aside their differences, come together as Americans first, and play for charity. As our national discourse has grown increasingly heated, this night of unity is more important than ever," he said.
