The 87-year-old justice, who has had four bouts with cancer, was experiencing a fever and chills and was initially evaluated at Sibley Memorial Hospital in Washington on Monday night. She then underwent a procedure at the hospital in Baltimore to clean out a bile duct stent placed in August.
Ginsburg is the oldest member of the Supreme Court and the anchor of its liberal wing. Nominated by President Bill Clinton, she has served on the high court for more than 25 years and across her tenure has battled numerous other health ailments.
Most recently, in early May, Ginsburg was hospitalized and treated for acute cholecystitis, described as a "benign gallbladder condition." She participated in oral arguments during her hospital stay, which were conducted by teleconference due to the coronavirus pandemic.
