The 86-year-old Ginsburg has returned to her home in Washington, D.C., and is "doing well," court spokeswoman Kathy Arberg said Sunday.

Ginsburg spent two nights at Johns Hopkins Hospital in Baltimore. She was taken there Friday after experiencing chills and fever.

The court says she received intravenous antibiotics and fluids and that her symptoms abated.

Ginsburg has had four occurrences of cancer, including two in the past year. She had lung cancer surgery in December and received radiation treatment for a tumor on her pancreas in August.
