Olympic gold medalist Simone Biles is blasting USA Gymnastics for failing to protect its athletes from sicko sports doctor Larry Nassar.

“I don’t mean to cry, but it’s hard coming here for an organization and having had them fail us so many times,” Biles, one of hundreds of women to accuse Nassar of sex abuse, said Wednesday while in Kansas City, Missouri, for the USA Gymnastics Championships, according to NBC affiliate KSHB-TV.

“We’ve done everything they asked us for even when we didn’t want to. And they couldn’t do one damn job,” said Biles, 22. “You had one job. You literally had one job and you couldn’t protect us.”

The star Olympian came forward in January 2018 to reveal that she was sexually abused by the former USA Gymnastics team doctor, who is behind bars for the rest of his life for his sex crimes.

Biles said the harrowing memories of the abuse still make it difficult for her to train, and some days she simply walks out of the gym.

“You feel everything at once. It hits you like a train wreck and it was really hard for me to train,” Biles said, adding, “It just breaks my heart to read it or to see it, so I just try to focus on my job, do what I’m supposed to, come out, compete, do what I love, and at the end of the day we just see.”

In a statement to the news outlet, USA Gymnastics president and CEO Li Li Leung said he knows the organization has “more to do.”

“Simone Biles is undoubtedly the best gymnast in the world and possibly of all time. She is an outstanding representative for gymnastics and the United States. We at USA Gymnastics have made a lot of progress in strengthening our athlete safety measures and putting our athletes first, but we know we have more to do,” the statement read.

“One of our goals is for our athletes to feel comfortable in speaking up and sharing their opinions, and we are listening to what they have to say. We will continue to work hard to demonstrate to Simone and all of our athletes, members, community and fans that we are working to foster a safe, positive and encouraging environment where athlete voices are heard. We join the rest of her fans and the sport in wishing her the best of success this week at the championships.”

Hundreds of women, including Olympians such as Aly Raisman and Gabby Douglas, have accused Nassar of sexually abusing them under the guise of medical treatment for decades.

Last week, an 18-month congressional investigation found that organizations like USA Gymnastics and the US Olympic Committee “had opportunities to stop Nassar but failed to do so.”
