The Supreme Court has announced that Supreme Court Justice Ruth Bader Ginsburg has been hospitalized.

The hospitalization stems from an infection caused by a gallstone.

According to Fox News:

Supreme Court Justice Ruth Bader Ginsburg was hospitalized with an infection caused by a gallstone, the court announced Tuesday, adding that she’s expected to remain in the hospital for a “day or two.”

Ginsburg, 87, underwent non-surgical treatment for acute cholecystitis, a benign gallbladder condition, at Johns Hopkins Hospital in Baltimore on Tuesday.

The justice had undergone outpatient tests at Sibley Memorial Hospital in Washington, D.C., Monday following oral arguments with the court, which confirmed that she had a gallstone blocking her cystic duct, resulting in an infection.

“The justice is resting comfortably and plans to participate in the oral argument teleconference tomorrow morning remotely from the hospital,” the Supreme Court said in a statement.

All oral arguments are being conducted via phone so it provides the opportunity for Ginsburg to participate while in the hospital.
