Six-time Olympic medalist Aly Raisman has joined the list of U.S. gymnasts who say they were sexually abused by Larry Nassar, the team's longtime doctor. Raisman describes the abuse during an interview on "60 Minutes" that will air Sunday and also talks about it in her new book, "Fierce," which comes out next week.
Raisman would not divulge exactly what Nassar did to her, but she did say that Nassar began treating her at the age of 15. She also said that she spoke to FBI investigators about him after last year's Olympics in Rio de Janeiro.
Raisman is the second member of the Fierce Five squad that won the team gold medal at the 2012 London Olympics to say she was sexually abused by Nassar.
