Supreme Court Justice Ruth Bader Ginsburg is reportedly recovering quickly from the fractured rib injury she sustained from a fall in her office, Reuters reported.

According to Ginsburg’s nephew Daniel Stiepleman, Ginsburg is “up and working” and “cracking jokes” from her hospital bed just hours after she was admitted to George Washington University Hospital Thursday morning with three fractured ribs. Ginsburg, who is the oldest Supreme Court justice at 85, fell while working in her office Wednesday evening.

“I can’t promise they were good jokes but they were jokes,” Stiepleman told Reuters Thursday evening from the premiere of his new documentary about one of his aunt’s most famous cases from 1972, “On the Basis of Sex.”
