Thomas, 73, was admitted on March 18 after experiencing flu-like symptoms, according to the court. He was diagnosed with an infection and treated with intravenous antibiotics.
Thomas was expected to be released no later than March 23 but the court had refused to say for over 36 hours whether Thomas remained in the hospital.
Thomas was released “earlier today,” Patricia McCabe, a spokeswoman for the court, told The Epoch Times in an email on Friday.
No other details were provided.
The court had said Thomas’s symptoms were abating and that Thomas was not suffering from COVID-19.
Ginni Thomas, the justice’s wife, has not returned requests for comment. Sibley Memorial Hospital, where Thomas was being cared for, declined a request for information on his condition.
Thomas missed three days of oral arguments due to his health issue but he plans on participating in the consideration and discussion of all the cases that were heard, Chief Justice John Roberts has said.
At the start of each day Thomas missed, Roberts said Thomas was “unable to be present today” but did not expand on the reason for the absences.
Thomas, appointed by President George H.W. Bush in 1991, is the longest-serving member of the nation’s top court and is poised to become its oldest later this year when Justice Stephen Breyer, 83, steps down.
Breyer told TMZ on Wednesday that he believed his colleague “is fine.”
