Raisman, 23, said she thought team doctor Larry Nassar, who spent almost 30 years with the organization and began treating her when she was just 15, was providing medical care.
The organization has taken some steps to provide more oversight and safety to its national team gymnasts. "We want to work with Aly and all interested athletes to keep athletes safe".
Raisman is the second member of the Fierce Five squad that won gold at the London Olympics who has said Nassar abused her.
Dr. Nassar spent over 20 years working with the US women's national gymnastics team and is now in jail after pleading guilty to charges of child pornography, but not guilty to charges of sexual assault.
Authorities revealed back in December of past year that they had discovered over 37,000 images and videos of child pornography featuring girls as young as six and a Go Pro video of Nassar molesting a group of young girls in a pool. "It's the right thing", she said. "I see these young girls that come up to me, and they ask for pictures or autographs, whatever it is ..."
"I want people to know: just because someone is nice to you and just because everyone is saying they are the best person, it is not okay for them to ever make you uncomfortable". She tells LaPook that she and other athletes didn't realize at the time that Dr. Nassar gained their trust through a predatory technique called "grooming", which builds emotional bonds between a predator and a victim. More than 130 women, many of them former athletes, have filed civil lawsuits alleging that Nassar sexually abused them under the guise of treating them for hip, back and other athletic injuries.
Among the accusers is another decorated gymnast, Raisman's 2012 teammate McKayla Maroney.
'It seemed whenever and wherever this man could find the chance, I was "treated".
"My mom and I are so close", she says.
She claimed that on the way to the world championship that year Nassar gave her a sleeping pill, and the she awoke to find him performing a "treatment" on her in the hotel. "You're so brainwashed to think, I thought he was so nice". That "treatment" began when Maroney was 13 and continued through her stellar performance at the 2012 Olympics.
It was after the Rio Games when she finally spoke with the Federal Bureau of Investigation, a move she claims left some in the sport angry at both her and her Final Five teammates. SO proud of you and your strength.
"I am angry. I'm really upset", Raisman told 60 Minutes. "Treatment sessions" with him always made me feel tense and uncomfortable". Even if he didn't do it to you, it's still the trauma and the anxiety of wondering what could have happened.
"He's a monster. It's so disturbing to think about what he did to me and so many other girls", Raisman said Monday. "She changed my life because she made me realize this is right thing, and if I can help one person then that's totally what it's all about". I didn't know what sexual abuse really was, ' said Raisman.
In light of the sex abuse scandal, USA Gymnastics adopted a series of reforms in June that it said will better prevent and respond to future cases of abuse.
"In the a year ago, Aly has become an advocate for many issues, and sharing her personal experience of abuse takes great courage", USA Gymnastics said.
The six-time Olympic medalist revealed the abuse during an interview with 60 Minutes that aired Sunday night and writes about her experience in her forthcoming book, Fierce.
She went on to state: 'Dr. I want these young girls to know.
The woman were joined on Tuesday by Dominique Moceanu, a 1996 gold medalist and teammate of Strug, who described a 'culture of fear, intimidation and humiliation, established by Bela and Marta Karolyi'.
