(JTA) — Six-time Olympic medalist Aly Raisman said that she was sexually abused by the women’s gymnastics national team doctor for decades.

Raisman, who is Jewish and is one of the most accomplished gymnasts in U.S. history, made the allegation against Dr. Larry Nassar in an interview scheduled to air Sunday on the CBS news magazine “60 Minutes,” as well as in her new book, Fierce.”

She is the second member of the gold medal-winning 2012 Olympic women’s team to accuse Nassar of abuse, the online edition of Time magazine noted in an article published Friday. In October, McKayla Maroney wrote on Twitter that Nassar molested her for years beginning when she was 13.

Nassar, who worked as a volunteer doctor for USA Gymnastics, is in jail awaiting sentencing after pleading guilty to child pornography charges in Michigan.

Raisman, 23, was 15 when she was first treated by Nassar, according to Sports Illustrated. The magazine reported that details of her experience appear in a biography set to appear next week.

Nassar also is named in more than 100 lawsuits filed by gymnasts and athletes he treated while working with USA Gymnastics and at Michigan State University. Those suits claim he sexually abused athletes under the guise of medical treatment. Nassar resigned from USA Gymnastics in the summer of 2015.

In the interview, Raisman said she spoke to FBI investigators about Nassar following the 2016 Olympic Games in Rio de Janiero after an investigation by the Indianapolis Star revealed that USA Gymnastics had a policy of not reporting sexual abuse reports unless they were filed by the victims or a parent. She won three medals at the Brazil games, including gold in the team overall.

Raisman, the nation’s second most decorated female Olympic gymnast, according to Time, is pushing for change at USA Gymnastics, which governs the sport and oversees the selection of world and Olympic teams.

“I am angry,” she said in the “60 Minutes” interview. “I just want to create change so [that young girls] never, ever have to go through this.”

In a statement to the program, USA Gymnastics said it has adopted new policies that require “mandatory reporting” of any potential abuse.

“USA Gymnastics is very sorry that any athlete has been harmed,” it wrote, adding that “we want to work with Aly and all interested athletes to keep athletes safe.”
