WASHINGTON (AP) — The Supreme Court said Tuesday that Justice Ruth Bader Ginsburg has been admitted to the hospital for treatment of a possible infection and will stay in the hospital for a few days following a medical procedure.

The court said in a statement that the 87-year-old Ginsburg went to a hospital in Washington on Monday evening after experiencing fever and chills. She underwent a procedure at Johns Hopkins Hospital in Baltimore, Md., on Tuesday afternoon to clean out a bile duct stent that was placed last August.

The statement said the justice “is resting comfortably and will stay in the hospital for a few days to receive intravenous antibiotic treatment.”
