The oldest justice on the Supreme Court is back on the bench on Nov. 18 after missing arguments due to an illness.
Ginsburg was at home with a stomach bug, Supreme Court spokeswoman Kathy Arberg said in a statement sent to reporters.
Ginsburg returned to the bench for a 10-minute session that saw new members being admitted into the court’s bar.
Ginsburg’s health is closely watched by people on both sides of the political aisle due to the possibility President Donald Trump could get his third Supreme Court nomination if she leaves.
Ginsburg has undergone multiple cancer treatments in recent years, one of them after she fell and broke her ribs. Doctors addressing the injury detected cancer in Ginsburg’s lungs, which was then treated.
Ginsburg was nominated by then-President Bill Clinton and has said she wants to serve until she’s at least 90.
Trump previously nominated Brett Kavanaugh and Neil Gorsuch, who were both confirmed.
Ginsburg has openly opposed Trump several times.
“I don’t want to think about that possibility, but if it should be, then everything is up for grabs,” Ginsburg said in an interview in July 2016.
Several days later, Ginsburg apologized, saying her remarks were “ill-advised.”
