Gymnasts Aly Raisman, McKayla Maroney and Gabby Douglas have publicly said they were abused by Nassar as well.
In February 2017, Nassar was charged in Michigan with 22 counts of criminal sexual conduct from his time working at Michigan State University. Five of those counts relate to victims who were under 13 years old.
Biles released a statement Monday on Twitter saying she too was one of the many survivors.
Biles' former teammate Raisman tweeted her support.
I am so proud of you. You are incredible Simone. I stand with you. I am shaking reading your post. I know we will all get through this together. https://t.co/Ziec5Fkhwv— Alexandra Raisman (@Aly_Raisman) January 15, 2018
Nassar is facing lawsuits filed by more than 125 women and girls, mostly gymnasts.
