Disgraced gymnastics doctor's alleged victims file new lawsuits

The disgraced former USA Gymnastics doctor is currently behind bars.

Thursday's legal move marks the first lawsuit against the International Federation of Gymnastics, the council that oversees competitive gymnastics on a global scale.

Attorneys allege that USA Gymnastics and others should have acted on allegations of Nassar's alleged abuse sooner, arguing that Nassar could have been stopped years earlier.

"The first report was made in 1997," Mo Aziz, one of the attorneys representing the alleged victims, said at a news conference Thursday.

"These young women were born in 1996, they do not have to be sitting here today," he added. "The hundreds of Mr. Nassar's victims would not have to exist had USAG, had Michigan State University and the other defendants responded appropriately."

Emily Vincent, one of the alleged victims who filed the suit, said in a press conference on Thursday that she was a 15-year-old high school swimmer when she was sexually abused by Nassar.

"How is change going to happen if people don't rally for it?" Vincent said. "This should never happen to anyone in the future and I want to be a part of making that a reality."

Victoria Carlson, another alleged victim, said at the news conference that she did not even identify herself as a victim of the physician's alleged sexual abuse until she read another women's account of her own.

"I never wanted to go public with this," Carlson said Thursday. "I actually never even wanted to tell my parents."

"I just signed your death warrant," Ingham County Circuit Judge Rosemarie Aquilina told Nassar at his sentencing two months ago.

USA Gymnastics told ABC News that it does not comment on pending legal matters.

"USA Gymnastics is sorry that any gymnast was harmed by the despicable crimes Larry Nassar committed," the group said in a statement. "The safety and well-being of our athletes are our highest priority and at the forefront of the decisions and actions that USA Gymnastics is taking to build a culture of empowerment that encourages our athletes to speak up, especially about difficult topics, and promotes a safe, positive training environment."

MSU did not immediately respond to ABC News' request for comment Thursday, but in a statement issued in February following Nassar's sentencing in January said that the sentencing "represents another important step toward justice. Over the past several days, many here at MSU, including President [Lou Anna] Simon and trustees, listened to the brave women who came forward to tell their stories at Nassar’s sentencing hearing."

The statement continued: "Nassar’s behavior was horrific and repugnant, and it is deeply disturbing to know that his crimes were often committed on campus. He will rightfully spend the rest of his life in prison.

Simon later resigned her post as MSU president.

The International Federation of Gymnastics did not immediately respond to ABC News' request for comment Thursday.
