Washington (CNN) Justice Ruth Bader Ginsburg fractured three ribs after falling in her Supreme Court office Wednesday night, the Supreme Court said in a statement.

According to the court, Ginsburg, 85, experienced discomfort after going home following the fall and was admitted to George Washington University Thursday morning for observation and treatment.

Admirers have recently nicknamed her "Notorious RBG," a play on the late rapper Notorious B.I.G., and have hailed her as a bulwark against conservative ideology -- and President Donald Trump -- because of her liberal opinions and dissents.

Ginsburg was not present at Thursday's investiture of Justice Brett Kavanaugh, Trump's appointee confirmed last month that gave the court a solid 5-4 conservative majority.
