Olympic gold-medal-winning gymnast McKayla Maroney alleges in a lawsuit filed in Los Angeles on Wednesday that USA Gymnastics paid her to be quiet about abuse by the team's longtime doctor Larry Nassar. The lawsuit ... also names as defendants Michigan State University, the US Olympic Committee and Nassar, the former team doctor who has admitted sexually abusing underage girls. "In December of 2016, after suffering for years from psychological trauma of her sexual abuse at the hands of Nassar, and in need of funds to pay for psychological treatment," Maroney was forced to enter into a confidential agreement with USA Gymnastics, the lawsuit said. John Manly, Maroney's attorney, called the confidentiality agreement "an immoral and illegal attempt to silence a victim of child sexual abuse. The US Olympic Committee and USA Gymnastics were well aware that the victim of child sexual abuse in California cannot be forced to sign a nondisclosure agreement as a condition of a settlement," he said. "Such agreements are illegal for very good reasons - they silence victims and allow perpetrators to continue committing their crimes." Maroney entered the settlement to "obtain funds necessary to pay for lifesaving psychological treatment and care," according to the lawsuit. Nassar was sentenced to 60 years in federal prison on child pornography charges earlier this month. In November, he pleaded guilty to seven counts of first-degree criminal sexual conduct and admitted to using his position to sexually abuse underage girls.
