Aly Raisman did not hold back in criticizing the the U.S. Olympic Committee as more and more stories of sexual abuse surrounding American gymnasts continue to come out.

Raisman, a three-time gold medalist, blasted the organization on Twitter for "shamelessly taking credit" for the resignations of three USA Gymnastics board members.

"Over the weekend, the USOC released a statement shamelessly taking credit for a few USAG resignations (note: not fired), as though they are addressing the problem," Raisman wrote. "But they're still not acknowledging their role in this mess. ZERO accountability. It's like none of us were ever abused!"

Raisman asked for separate investigations into USOC and USA Gymnastics for their negligence of the safety of young gymnasts.

"For the past week, survivors came forward to courageously face a perpetrator of evil and to share their painful stories," Raisman wrote. "Many of them, myself included, claim the USOC is also at fault. Was the USOC there to 'focus on supporting the brave survivors'? No. Did they issue any statement then? Crickets ...."

Chairman Paul Parilla, vice chair Jay Binder and treasurer Bitsy Kelley all said they were resigning Monday, and USA Gymnastics suspended the coach of the 2012 Olympic team, John Geddert, later in the day.

Geddert and Larry Nassar, the doctor accused of sexually abusing dozens of young gymnasts, worked closely together at Nassar's facility in Michigan.

Nassar has already been sentenced to 60 years on child pornography charges and is in his second week of hearing victim testimonials from the women accusing him.
