His risk of death is "substantially lower" than it was when he was admitted to the hospital on Wednesday, and "I think that an excellent recovery is a good possibility", Sava said.
The congressman underwent another surgery Saturday, and the hospital said he was more responsive and speaking with family. He has been sedated, but has been brought out of sedation periodically and been able to recognize and communicate with his family, Sava said. His family said in a statement Saturday that Mika had undergone another operation and was expected to recover fully, according to NBC News.
The gunman, identified by law enforcement officials as 66-year-old James Hodgkinson of Belleville, Illinois, later died from injuries sustained during a shootout with police on the scene.
For now, Scalise remains in critical condition in the hospital's intensive care unit. After Scalise was shot in the hip, the bullet traveled through his pelvis, fractured bones and injured internal organs.
A list with several names of Congress members written on it was reportedly found with the man suspected of opening fire at a GOP baseball practice on Wednesday, according to several reports.
The shot fired at Scalise left perhaps hundreds of bullet fragments internally, many of which may never be removed because surgery might be more risky than leaving them in place, Sava said.
Hospital officials said it is hard to predict how long the congressman will be in the hospital, but that he is expected to be able to walk and hopefully run after a period of rehabilitation.
"My dear friend Steve Scalise took a bullet for all of us and because of him - and all the tremendous pain and suffering he has endured, he is having a hard time, far worse than anyone thought - our country will perhaps become closer, more unified, so important", Trump said.
The House majority whip remains in serious condition at Medstar Washington Hospital Center. 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. Mo Brooks of Alabama, Jeff Duncan of SC, and Trent Franks of Arizona.
Bailey was spotted Friday back in the Capitol building, on crutches and out of uniform, accepting congratulations from fellow officers.
The person says investigators aren't sure of the significance of the names and it's not clear whether this was a list of people the attacker was targeting.
