Olympian Aly Raisman has accused former USA Gymnastics doctor Larry Nassar of sexual abuse, CBS News reported. Raisman, who has won six Olympic medals, including three gold, said Nassar started treating her when she was 15 years old. “I am angry,” she said in a CBS News 60 Minutes interview. “I'm really upset because it's been—I care a lot you know, when I see these young girls that come up to me, and they ask for pictures or autographs, whatever it is, I just—I can't—every time I look at them, every time I see them smiling, I just think—I just want to create change so that they never, ever have to go through this.” Last month the gymnast’s former Olympic teammate, McKayla Maroney, accused Nassar of sexually abusing her since she was 13-years old. Nassar, who worked with U.S. women's gymnastics for more than 20 years, is already in jail after pleading guilty to child pornography charges. More than 130 women have also filed civil lawsuits accusing him of sexual abuse.
