The USA Gymnastics sex abuse scandal involves the sexual abuse of female athletes—primarily minors—by Larry Nassar, a former USA Gymnastics national team osteopathic physician. He is named in hundreds of lawsuits filed by athletes who said that Nassar sexually abused them under the pretense of providing medical treatment. Since the first public statements were made in September 2016, more than 150 women, including former USA Gymnastics national team members Jamie Dantzscher, Jeanette Antolin, McKayla Maroney, Aly Raisman, Maggie Nichols, Gabby Douglas, Simone Biles, and Jordyn Wieber, have accused Nassar of sexually abusing them. It is one of the biggest sexual abuse scandals in sports history.
On July 11, 2017, Nassar pleaded guilty to federal child pornography charges; he was sentenced to 60 years in prison on December 7, 2017. On November 22, 2017, he pleaded guilty to seven charges of first-degree sexual assault and entered another guilty plea a week later to three additional charges of sexual assault. On January 24, 2018, Nassar was sentenced to 40 to 175 years in prison, set to run after Nassar serves the 60-year federal prison sentence for child pornography.
USA Gymnastics and Michigan State University—where Nassar was a faculty member—have been accused of enabling Nassar's abuse and are named as defendants in civil lawsuits that former gymnasts have filed against Nassar.
Larry Nassar was a licensed osteopathic physician and the national team sports-medicine doctor for USA Gymnastics. He also ran a clinic and gymnastics club at Michigan State University, where he was a faculty member. USA Gymnastics fired Nassar in 2015 "after learning of athlete concerns."
