James T. Hodgkinson, 66, allegedly opened fire on a Congressional baseball team as Republicans were practicing for an annual game to be played at Nationals Park Thursday.
Scalise, 51, sustained injuries to internal organs, broken bones and severe bleeding after being shot in his left hip early on Wednesday at a baseball field in a suburb of Washington.
"We are encouraged by improvement in his condition in the last 36 hours", Jack Sava of MedStar Washington Hospital Center told reporters at a news conference. He has been sedated, but has been brought out of sedation periodically and been able to recognize and communicate with his family, Sava said. Congressional aide Zack Barth, Tysons Food lobbyist Matt Mika and Capitol Police Officer David Bailey were also shot in the attack, but have since been released from the hospital.
Sava said Friday that there are hundreds of bullet fragments in Scalise's body, but "we have no intention to try and remove all the bullet fragments at this point". Griner remains hospitalized at MedStar Hospital after getting shot in the ankle, and Sava described her in good condition.
President Donald Trump said Friday that Steve Scalise "took a bullet for all of us".
In a statement posted to his Twitter account, Mr Scalise was said to be "more responsive, and is speaking with his loved ones".
Scalise will need more operations for his injuries, but doctors can't yet predict how many are necessary.
The president says that because of the "tremendous pain and suffering he's now enduring. our country will perhaps become closer, more unified".
Mr Scalise was among five people wounded in the shooting. Scalise was hit as a gunman sprayed bullets into a GOP congressional baseball practice outside Washington D.C.
Since then, the lawmaker has undergone multiple surgeries and procedures to stop the bleeding and fix bone. The president made his comments as he spoke in Miami to announce a new policy on Cuba.
House Speaker Paul Ryan has paid a visit to wounded Majority Whip Steve Scalise at the hospital.
The Louisiana Republican was shot in the hip Wednesday morning in the baseball practice shooting by an IL man with grudges against President Donald Trump and the GOP. He's been undergoing repeat surgeries.
Lawmakers went ahead with the charity baseball game on Thursday to honor Scalise.
