One of the best gymnasts in the world and Olympic gold winner Simone Biles broke down in tears as she testified on how USA Gymnastics doctor Larry Nassar molested her.

The United States Olympic and Paralympic Committee and USA Gymnastics, two organizations Congress created to safeguard athletes, “failed to do their jobs,” according to Biles, 24, who made this claim in her opening statement on Wednesday.

She and three other US gymnasts spoke before the Senate judiciary committee, saying “enough is enough” as they discussed the long-lasting effects that Nassar’s actions had on their lives.

With her voice choked with emotion, Biles added, “I don’t want another young gymnast, or Olympic athlete, or any individual to experience the horror that I and hundreds of others have endured before, during and continuing to this day in the wake of the Larry Nassar abuse.”

Politicians are looking into the FBI investigation’s flaws, including as the delays that enabled Nassar to assault more athletes.

In July, an internal Justice Department inquiry found that when USA Gymnastics first brought the claims to the FBI’s Indianapolis field office in 2015, the investigation was flawed fundamentally and that the issue was not handled with “utmost seriousness.”

He continued to treat gymnasts at Michigan State University, a high school, and a gymnastics club until September 2016, the study concluded, despite the fact that gymnasts initially reported the sexual assault claims to the FBI in 2015.

In response to abuse allegations made by more than 150 children and women, Nassar, 58, was given a sentence of up to 175 years in prison.

After reading the report, Biles said that she believed the FBI “turned a blind eye to us.”

“We suffered and continue to suffer because no one at FBI, USAG or the USOPC did what was necessary to protect us,” she said. “We have been failed, and we deserve answers. Nassar is where he belongs, but those who enabled him deserve to be held accountable. If they are not, I am convinced that this will continue to happen to others across Olympic sports.”

Ms. Biles was noticeably saddened when she appeared with other athletes including Aly Raisman, McKayla Maroney, and Maggie Nichols.

Maroney, a former gymnast, gave a vivid account of Nassar’s torture.

‘The first thing Larry Nassar ever said to me was to change into shorts with no underwear because that would make it easier for him to work on me, and within minutes, he had his fingers in my vagina,’ Maroney said.

‘The FBI then immediately asked, “Did he insert his fingers into your rectum?” I said, “No, he never did”. They asked if he used gloves. I said, “No, he never did”. They asked if this treatment ever helped me. I said, “No, it never did”. This treatment was 100 percent abuse and never gave me any relief.’

Maroney said that Nassar gave her a sleeping drug for the flight when she traveled to Tokyo so he could “work on me later that night.”

“That evening, I was neked, completely alone, with him on top of me, molesting me for hours. I told [the FBI] I thought I was going to die that night because there was no way that he would let me go. But he did,” said Maroney, who went on to list several other occasions when Nassar had abused her.

Maroney said that the FBI not only “minimized” but also “silenced” her and falsified her report.

Chris Wray, the director of the FBI, offered no justifications and said that the agency had dismissed one of the agents who had fabricated information in Maroney’s 2015 interview about the assault.

He subsequently said that the behavior of the agents who mishandled the investigation “was beyond the pale,” adding that “on no planet is what happened in this case acceptable.”

“I blame Larry Nassar and I also blame a entire system that enabled and perpetrated his abuse,” Ms. Biles, who identified herself as a victim of sexual abuse, said.

Wray expressed regret to the gymnasts for the way the agency handled the Nassar investigation.

Wray stated, “I am deeply and profoundly sorry to each and every one of you.”

‘I am sorry that so many people let you down over and over again and I am especially sorry that there were people at the FBI who had their own chance to stop this monster back in 2015 and failed, and that is inexcusable, it never should have happened, and we are doing everything in our power to make sure it never happens again.’

Ms. Biles also discussed how the abuse had damaged her this summer’s Tokyo Olympics, when she had to withdraw from five final events due to mental health issues.

Biles said: “As the lone competitor in the recent Tokyo Games who was a survivor of this horror, I can assure you that the impacts of this man’s abuse are not ever over or forgotten.

“This meant I would be going to the gym, to training, to therapy, living daily among the reminders of this story for another 365 days.”

The Justice Department’s Inspector General Michael Horowitz published a damning report in July that criticized the FBI for mishandling its probe in a sequence of mistakes that enabled the abuse to go unchecked for months before the hearing on Wednesday.
