Aly Raisman, one of the Olympic gold-medal-winning gymnasts who said she was sexually abused by Larry Nassar, blasted the U.S. Olympic Committee on Twitter, chiding the organization for "shamelessly taking credit" for the resignations of three top board members at USA Gymnastics.

Raisman, in a lengthy statement posted Monday night on Twitter, called for an independent investigation of both the USOC and USA Gymnastics and concluded her thoughts by writing, "What's it going to take for you to do the right thing?"

Chairman Paul Parilla, vice chair Jay Binder and treasurer Bitsy Kelley announced they were stepping down Monday as testimony in Nassar's sentencing hearing in Michigan moved into its second week. Nassar faces a minimum prison sentence of 25 to 40 years in a molestation case.

Later Monday, USA Gymnastics suspended the coach of the 2012 Olympic team, John Geddert, who worked with Nassar at his gyms in Michigan.

"For the past week, survivors came forward to courageously face a perpetrator of evil and to share their painful stories," Raisman wrote on Twitter. "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 ...."

Raisman, a three-time gold medalist from the 2012 and 2016 Summer Games, already revealed her abuse in a series of media interviews.

Raisman was among the numerous women who delivered impact statements last week in Nassar's case. At one point, she addressed new USAG president and CEO Kerry Perry.

"Talk is cheap," she said. "I have never met you and I know you weren't around for most of this. ... Unfortunately, you have taken on an organization that I feel is rotting from the inside."
