Supreme Court Justice Ruther Ginsburg was admitted to The Johns Hopkins Hospital in Baltimore on Tuesday for treatment of a possible infection.

Ginsburg was initially evaluated at Sibley Memorial Hospital in Washington, D.C., on Monday night after experiencing fever and chills. She underwent an endoscopic procedure at Johns Hopkins on Tuesday afternoon to clean out a bile duct stent that was placed last August, the court said.
