“The last I heard, she was up and working -- of course, because what else would she be doing? -- and cracking jokes,” Stiepleman said at the premiere of the film “On the Basis of Sex,” a movie about Ginsburg’s life. “I can’t promise they were good jokes, but they were jokes.”

Ginsburg was hospitalized one day after she fell in her office at the Supreme Court, officials said. Tests done at George Washington University Hospital showed she had three fractured ribs and doctors admitted her to the hospital for observation.

The Supreme Court is scheduled to hear its next arguments on Nov. 26.

Original report: Ginsburg, 85, fell Wednesday evening while in her office.

“She went home, but after experiencing discomfort overnight, went to George Washington University Hospital early this morning,” court officials said Thursday in a statement. “Tests showed that she fractured three ribs on her left side and she was admitted for observation and treatment.”

Ginsburg broke two ribs in a fall in 2012. She has had two prior bouts with cancer and had a stent implanted to open a blocked artery in 2014.
