Raisman says Nassar abused her

Former USA Gymnastics doctor Larry Nassar in court in June

The organization said it recently adopted a new "safe sport policy" that requires "mandatory reporting" of suspicions of sexual abuse and also sets standards to "prevent inappropriate interaction" between athletes and adults.

Larry Nassar is accused of multiple sexual abuse on gymnasts for almost 20 years.

As part of the 60 Minutes interview, Raisman said, "Why are we looking at why didn't the girls speak up?"

The first public accusations against Nassar came a little more than a year ago, and more than 130 women have filed suits accusing Nassar of sexual assault. Raisman asked.

Raisman revealed the sexual abuse by Nassar in a preview on Friday of an interview to be aired in full on Sunday on the CBS show "60 Minutes".

Raisman, 23, will also be exposing the sick details of the alleged abuse on her memoir, Fierce.

"I am angry. I'm really upset because it's been..." USA Gymnastics, in a statement to "60 Minutes", said it is "very sorry that any athlete has been harmed".

More than 140 women are suing Nassar and his former employer, Michigan State University. "We are grateful to the athletes that brought their concerns about Dr. Nassar to USA Gymnastics".

Nassar pleaded guilty to federal child-pornography charges in June and has been accused by more than 100 women and girls of sexual assault.

It is also reported he still faces 33 charges of criminal sexual conduct in MI. If convicted on any one of the 22 counts of first-degree criminal sexual conduct, Nassar could be sentenced to life in prison. I can't. Every time I look at them, every time I see them smiling, I just think ...

The scandal in the sport led to the resignation of USA Gymnastics chief executive Steve Penny in March of this year.

It was commissioned by USA Gymnastics and conducted by Deborah Daniels, a former Federal prosecutor, who spent a significant portion of her career prosecuting child sexual offenders, and scrutinised the organisation's methods. "These girls, they should be comfortable going to USA Gymnastics and saying 'I need help, I want therapy".
