Another major Team USA gymnastics star claims she was abused by ex-USA Gymnastics doctor Larry Nassar -- with Aly Raisman coming forward in the hopes of protecting future athletes.
Raisman -- a 2-time national team captain who won 6 gold medals -- opened up about the allegations to "60 Minutes" ... saying she met with the FBI after the '16 Rio Olympics.
23-year-old Raisman wouldn't get into the specifics of the alleged abuse -- she would only say she's very "angry" and looking for justice.
Nassar has been accused of sexually abusing scores of female athletes over the years -- including McKayla Maroney.
Most of the women claim Nassar violated their genitals -- and claimed he was performing routine medical procedures.
