Supreme Court Justice Clarence Thomas, 73, has been hospitalized with an infection since Friday and is expected to be released in the next few days, according to the court.
"Thomas was admitted to Sibley Memorial Hospital in Washington DC on Friday evening after experiencing flu-like symptoms," the Supreme Court said in a statement Sunday evening.
The court's statement read, "He was tested, diagnosed with an infection, and is being treated with intravenous antibiotics. His symptoms are subsiding, he is resting well, and he has Expect to be released from the hospital in a day or two."
The court said that during his absence from Supreme Court proceedings, Justice Thomas would continue to engage in "consideration and discussion" of cases based on written material and recordings of oral arguments. Judges will hear oral arguments on Monday, Tuesday and Wednesday.
Thomas is one of the High Court's conservative veterans and has served for more than 30 years, longer than any other current justice.
The court did not explain why it waited two days to disclose the news. As NPR's Nina Totenberg pointed out, the health of Supreme Court justices is often shrouded in mystery.
