House Majority Whip Steve Scalise, R-La., has been readmitted to the intensive care unit at MedStar Washington Hospital Center and is listed in "serious" condition after concerns emerged about possible infection as he continues recovery from a gunshot during practice for the Congressional Baseball Game on June 14.

"Congressman Steve Scalise has been readmitted to the Intensive Care Unit at MedStar Washington Hospital Center due to new concerns for infection," the hospital said in a statement late Wednesday night. "His condition is listed as serious."

Scalise had been upgraded to fair condition following several surgeries on June 21. During practice for the game, he was shot by James T. Hodgkinson and sustained a rifle shot to the left hip. The bullet fractured bones, injured internal organs and caused severe bleeding, leading Dr. Jack Sava, the trauma director at MedStar, to say that he faced an "imminent risk of death" when he arrived at the hospital after the shooting.

Sava said in a press conference two days after the shooting that infection was a concern moving forward for the Louisiana Republican's recovery. However, at the time, he said that he expected Scalise to make an "excellent" recovery.

Scalise was one of four shot in the incident exactly three weeks ago, including congressional staffer Zach Barth, Capitol Police special agent Crystal Griner, and Tysons Food lobbyist Matt Mika, who was recently released from the hospital.

MedStar Washington Hospital Center added it would provide another update on Thursday.
