Raisman also slammed the USOC for "shamelessly taking credit" for the resignation of three USAG board members on Monday.
Michigan State has been in the national media spotlight in the last week for its handling of sexual assault allegations against Nassar, who was a team doctor with the women's gymnastics team and other student-athletes.
"Given Nassar's conviction, sentencing hearings, and the fact that his videos show him in physical contact with young women in his capacity as a USA Gymnastics doctor, we've made a decision to remove his channel", YouTube told the Reporter in a statement. He has already been sentenced to 60 years in federal prison for child pornography and faces at least 25 additional years for sexual assault charges.
Those stepping down are chairman Paul Parilla, vice chairman Jay Binder and treasurer Bitsy Kelley.
USA Gymnastics has been criticized by Olympic gold medalists Aly Raisman, McKayla Maroney, Simone Biles and Jordyn Weiber - all of whom allege Nassar molested them. Numerous victims were teenagers when they were sexually abused by Nassar, with his hands, during medical treatment.
Nassar's victims have not only taken aim at him and Michigan State, but also USA Gymnastics and the U.S. Olympic Committee - organizations they believe mishandled complaints about him.
A number of Olympians have been among those testifying in the Nassar hearing.
Survivors and others have described a culture of secrecy and a solitary focus on sporting glory at USA Gymnastics.
When some of the abuse cases came to light, the federation and its lawyers sought to silence athletes with hush-money agreements.
Last week, Ms Raisman addressed Nassar in the court, saying: "I love this sport, and that love is stronger than the evil that resides in you, in those who enabled you to hurt many people".
