The court says Ginsburg was initially evaluated at Sibley Memorial Hospital in Washington before being transferred to Johns Hopkins for further evaluation and treatment of any possible infection. Last week she had the stomach bug, but more importantly, she has been treated for cancer twice in the previous year.
After being medicated with intravenous antibiotics and fluids, Ginsburg's symptoms abated and it was anticipated that she would be released from the hospital as early as Sunday morning.
She recently missed a day of oral arguments at the court with what a spokeswoman called a stomach bug.
Ginsburg has dealt with health issues over the last 20 years, including several battles with cancer.

Ginsburg reportedly felt "chills and fever" earlier in the day.
Ginsburg has been treated for cancer twice in the past ten months.
