(JTA) – Aly Raisman sued the U.S. Olympic Committee and USA Gymnastics alleging negligence for not stopping former U.S. Olympics gymnastics team doctor Larry Nassar from sexually abusing young athletes. Raisman, who is Jewish and the winner of numerous Olympic medals, including several golds, filed her lawsuit Wednesday, Feb. 28 in California, saying they “knew or should have known” about abusive patterns Nassar, who is now in prison. The lawsuit is the latest development in Raisman’s campaign for raising awareness of sexual abuse in sports. Raisman was among dozens of young female gymnasts Nassar has pleaded guilty to molesting. The filing alleges negligence by the USOC and USA Gymnastics for failing to make sure appropriate protocols were followed in regard to monitoring Nassar, who is named as a co-defendant in the lawsuit. Nassar has been sentenced to a at least 140 years in prison.

Raisman said the USOC and USA Gymnastics allowed Nassar to continue abusing athletes by not telling the university about the conduct that led them to fire him. The USOC is conducting an independent review of when former CEO Scott Blackmun and others learned the details about abuse cases at USA Gymnastics and whether they responded appropriately. Blackmun stepped down earlier this week to deal with prostate cancer. Raisman, several high-profile gymnasts and two U.S. senators had been calling for his ouster for weeks.
