Supreme court justice Ruth Bader Ginsburg is up and working as she recuperates from cancer surgery.
A spokeswoman for the court, Kathy Arberg, also said Ginsburg remained in New York at Memorial Sloan Kettering cancer center on Sunday. No information has been released on when Ginsburg might return home.
Ginsburg had surgery on Friday to remove two malignant growths in her left lung. Doctors said there was no evidence of any remaining disease.
The 85-year-old has been treated for cancer on two other occasions. Last month she cracked three ribs in a fall at the court.
The court next meets on 7 January. Despite her health problems, Ginsburg has never missed arguments.
Ginsburg is the most prominent justice among what is considered the liberal wing of the court.
She was appointed by Bill Clinton during his presidency and took the oath of office on 10 August 1993. She was only the second female justice to be confirmed to the supreme court, after the groundbreaking appointment of Sandra Day O’Connor.
Only four women have ever been confirmed to the court and Ginsburg sits with two other women on the nine-member bench, alongside Sonia Sotomayor and Elena Kagan, who were both appointed by Barack Obama.
