Scalise, 51, a police officer, a congressional aide and a lobbyist were wounded on Wednesday when a man identified as James Hodgkinson, 66, from the St. Louis suburb of Belleville, Illinois, opened fire on the lawmakers who were practicing for an annual charity baseball game between Republicans and Democrats.
The Democrats won the game, 11-2. Doyle gave the winning trophy back to the Republicans to put in Scalise's office. "That is the source of unity, and more than ever, we must embrace it".
Sponsors spent nearly $188 million lobbying Congress and the federal agencies past year, according to a compilation of data from the Center for Responsive Politics, a Washington-based research group.
Later, the crowd burst into applause as Capitol Police Officer David Bailey - who was injured as he pursued the shooter - hobbled to the mound on crutches and tossed the ceremonial first pitch.
"Look, I signed up for this but my 3-year-old didn't and our families didn't", Richmond added.
When the members of the Republican team were announced at Nationals Park, mention of Scalise's name drew a standing ovation from the areas designated for Republican, Democrat and nonpartisan fans alike.
"In Washington, we have our disagreements, but we all agree that we are here to serve this nation we love and the people who call it home", Trump said. Most say they don't need extra security, while others say for certain events, they wouldn't mind the extra security.
The game, which dates to 1909 and is a summertime tradition on Capitol Hill, is a rare example of bipartisanship in an increasingly polarized Washington.
Scalise, who underwent a third surgery Thursday, is listed in critical condition after being shot through the hip.
Lawmakers went ahead with the charity baseball game on Thursday to honor Scalise. It's about Americans coming together to support a good cause.
Mr. Trump could not attend because there wasn't enough time for the Secret Service to organize security, according to the White House, but his daughter Ivanka Trump was in attendance, as were some members of the Trump administration. "He is grateful for the courageous actions of U.S. Capitol Police, first responders, and colleagues", his office revealed in a previous statement.
