U.S. Supreme Court Justice Ruth Bader Ginsburg was hospitalized Thursday after fracturing three ribs in a fall.
A court spokeswoman says Ginsburg fell in her office Wednesday night.
The 85-year-old justice initially went home, but experienced discomfort overnight and was admitted to George Washington University Hospital Thursday morning.
According to the spokeswoman, tests showed she fractured three ribs on her left side.
Ginsburg has served on the court since 1993.
She's the oldest of the nine justices and one of the court's four liberals.
The court's 5-4 conservative majority was restored last month after the Senate confirmed Brett Kavanaugh following a contentious nomination process.
If Ginsburg were unable to continue serving on the court, President Trump would likely move swiftly to replace her - most likely with another conservative.
Trump was scheduled to go to court on Thursday for a formal ceremony seating Kavanaugh.
