A gold-medal winning Olympian has confronted disgraced USA Gymnastics doctor Larry Nassar at his sentencing to reveal he abused her, too. Jordyn Wieber is the fourth member of the Fierce Five, the winning 2012 Summer Olympics squad, to accuse him. She joins teammates Aly Raisman, Gabby Douglas and McKayla Maroney, who all said Nassar, 54, molested them.
