Former President Bill Clinton was admitted to a Washington, D.C. hospital on Monday after he developed a fever.
He was admitted to MedStar Georgetown University Hospital on Monday for “testing and observation,” his deputy chief of staff Angel Ureña said, according to The Associated Press.
Update 11:45 a.m. ET, Dec. 24: Clinton, according to a post on X by Ureña, was released from the hospital Tuesday morning. He had the flu.
Original report: Ureña added that Clinton, 78, was in “good spirits and deeply appreciates the excellent care he is receiving.”
The cause of the fever has not been disclosed. And a source told NBC News that it was “not urgent.”
The former president was expected to spend at least one night in the hospital, CNN reported.
This is not the first time he has been admitted to a hospital for a medical condition. He had a quadruple bypass in 2004, a partially collapsed lung in 2005, stent implants in 2010 and a “non-covid-related infection” in 2021, The Washington Post and the AP reported. The 2021 illness was a urological infection that hit his bloodstream but he did not go into septic shock.
Clinton recently published his latest book, “Citizen: My Life After the White House” and had been traveling to promote it, CNN reported.
