Trump, who visited Scalise at the MedStar Washington Hospital Center on Wednesday evening, expressed optimism that Scalise would eventually recover.
Family members of Matt Mika say the MI native was shot multiple times in his chest and arm, and he remains in the intensive care unit in critical condition at George Washington University Hospital.
James T Hodgkinson, 66, died after a shootout with police on Wednesday after he opened fire at a sports field in Alexandria, Virginia, where Republican lawmakers and their aides were training for a charity baseball game.
"The bullet travelled across his pelvis, fracturing bones, injuring internal organs, and causing severe bleeding", the statement said. Because Scalise is a member of House leadership, Capitol Police were present at the field.
Earlier Thursday, Republican lawmakers met behind closed doors to share reflections and pray. They also signed oversized cards sending well wishes to those who were injured in the shooting, including Rep. Steve Scalise of Louisiana.
Although the weather in Washington looks headed toward a near-flawless summer night, an obvious and immovable shadow is being cast over Thursday night's Congressional Baseball Game - a tradition that began more than a century ago.

He said one of the key measures would aim at preventing the incitement of "hate and terrorism" on the internet. Article 50 allows for two years of talks to decide an European Union member state's separation terms.
So far, investigators have not linked Hodgkinson to any radical groups, said a law enforcement official who spoke on condition of anonymity because the official was not authorized to discuss the investigation publicly.
"We may have our differences, but we do well in times like these to remember everyone who serves in our nation's capital is here because, above all, they love our country", Trump said during a statement delivered in the Diplomatic Room of the White House.
The annual Congressional Baseball Game, which dates to 1909 and is a summertime tradition on Capitol Hill, will be played Thursday despite Wednesday's shooting at the GOP squad's practice in Alexandria, Virginia. "We love you." Lewis led a House floor Democratic sit-in previous year when Republicans refused to consider gun control legislation. Rep. Roger Williams of Texas and Special Agent David Bailey of the U.S. Capitol Police sustained minor secondary injuries.
Politico reports that former congressional staffer Matt Mika also remains in critical condition following multiple gunshot wounds to the chest.
In the hours after the shooting, Republicans and Democrats alike struggled to reassess their protection and engagement with the public, outside the protective bubble of the Capitol.
Brooks, R-Huntsville, said this morning when events like Wednesday's shooting happen, "We can't let the bad guys gain a psychological victory".
Trump Responds to WashPo Obstruction of Justice Bombshell: 'Phony Story. Nice'
Last week, Comey testified in a Senate hearing that he believed he was sacked "because of the Russian Federation investigation". The Post's report is based on conversations with five unnamed people who are said to have been briefed on the matter.
Federal Bureau of Investigation special agent Tim Slater declined to comment on whether the gunman had a vendetta against Republicans.
The gunman had a rifle and "a lot of ammo", said Sen.
Colleagues said Scalise, who had been fielding balls at second base, dragged himself away from the infield, leaving a trail of blood before they rushed to his assistance.
He said Democrats probably contributed to Hodgkinson "believing he was a patriot trying to protect Americans" from Republicans. Capitol Police Officer Crystal Griner is also a patient at that facility.
Since the shooting, members of Congress have spoken about a need for unity, at a time when polarization seems to be at an all-time high.
Mr Trump said Mr Scalise was "a true friend and patriot". The last time a lawmaker was shot was when Democratic Rep. Gabby Giffords was targeted by a gunman in 2011.

They remained at large Thursday morning. "You don't shoot at a man carrying his 10-month-old son", the police chief said. Police say the father ran up to the driver of a auto nearby and yelled for help. "He was yelling, 'Help me".
