The court announced he was admitted Friday night with flu-like symptoms.
According to the Associated Press:
Thomas, 73, has been at Sibley Memorial Hospital in Washington, D.C., since Friday after experiencing “flu-like symptoms,” the court said in a statement. He does not have COVID-19.
The court offered no explanation for why it waited two days to disclose that the justice was in the hospital.
It also provided no additional details about the infection, but said Thomas is being treated with antibiotics and his symptoms are abating.
He could be released in the next couple of days, the court said.
The Supreme Court is meeting this week to hear arguments in four cases. Thomas plans to participate in the cases even if he misses the arguments, the court said.
Thomas has no known health conditions, but justices make their own decisions about what health information to release and when.
Justice Clarence Thomas is currently the longest-serving member of the Court.
