Olympic gold medalist Aly Raisman says that she was sexually abused by her teams disgraced former doctor, Larry Nassar.

In an interview with CBS 60 Minutes set to air on Sunday, Raisman says shes angry that USA Gymnastics didnt address sooner the rampant allegations against Nassar. More than 100 women and girls , including Raismans teammate McKayla Maroney , have accused the former USA Gymnastics doctor of sexual abuse spanning decades.

Why are we looking at why didnt the girls speak up? Raisman said of people who have asked why the athletes didnt speak out earlier. Why not look at what about the culture? What did USA Gymnastics do, and Larry Nassar do, to manipulate these girls so much that they are so afraid to speak up?

Raisman has spoken out about Nassar before, but has never accused him of abusing her.

The statistics are just alarming, its one in four girls are sexually abused, and those are just the girls that speak up and that was from a couple of years ago, she told People magazine in April. I cant tell you how many girls I know that have been sexually abused at some point in their life and its so sad.

Nassar pleaded guilty to child pornography charges in July and is awaiting sentencing.

In a statement Friday morning , USA Gymnastics said it was appalled by the conduct of which Larry Nassar is accused, and... very sorry that any athlete has been harmed during her or his gymnastics career.
