Supreme Court Justice Ruth Bader Ginsburg is up and working as she recuperates from cancer surgery, The Associated Press reported Monday.
Ginsburg, the eldest justice on the US Supreme Court, underwent surgery on Friday to remove two malignant nodules on her left lung. The surgery took place at the Memorial Sloan Kettering Cancer Center in New York.
A spokeswoman for the court, Kathy Arberg, told AP on Monday that Ginsburg remained in New York at Memorial Sloan Kettering Cancer Center on Sunday. No information has been released on when Ginsburg might return home.
Now 85, the justice has been treated for cancer two other times.
Last month, she cracked three ribs in a fall at the court. The Jewish judge was discharged from the hospital the next day and was back at her notoriously vigorous workouts within a week.
The justice, who was appointed by President Bill Clinton in 1993, is one of four liberals on the nine-member court.
Since taking office, President Donald Trump has had the opportunity to replace two retiring justices, tipping the balance in the conservatives' favor.
Ginsburg had a fall out with Trump before he was elected, when she said in interviews she "can't imagine what the country would be" with Trump as president.
She later acknowledged her comments were “ill-advised” and added, “Judges should avoid commenting on a candidate for public office. In the future I will be more circumspect.”
The court's oldest justice, Ginsburg is a liberal stalwart who has said she will not retire as long as she feels she can do the work.
The court next meets on January 7. Despite her health problems, Ginsburg has never missed arguments.
