“Justice Ginsburg was admitted to The Johns Hopkins Hospital in Baltimore, Maryland early this morning for treatment of a possible infection,” spokeswoman Kathleen Arberg said Tuesday. “She was initially evaluated at Sibley Memorial Hospital in Washington, D.C. last night after experiencing fever and chills. She underwent an endoscopic procedure at Johns Hopkins this afternoon to clean out a bile duct stent that was placed last August. The Justice is resting comfortably and will stay in the hospital for a few days to receive intravenous antibiotic treatment.”

It’s the latest development in Ginsburg’s lengthy history of medical issues while serving on the high court.
