McKayla Maroney: I Was Drugged and Molested By Team USA Doctor

McKayla Maroney says she was sexually assaulted by the team doctor for the U.S. women's gymnastics team and Olympic team -- and the abuse started when she was 13 years old.

The former U.S. Olympic gymnast went public about the alleged abuse Wednesday morning -- saying Dr. Larry Nassar repeatedly molested her under the guise of administering "treatment."

The 21-year-old says, "Dr. Nassar told me that I was receiving 'medically necessary treatment that he had been performing on patients for over 30 years.'"

"It started when I was 13 years old, at one of my first National Team training camps, in Texas, and it didn't end until I left the sport."

"It seemed whenever and wherever this man could find the chance, I was 'treated.' It happened in London before my team and I won the gold medal, and it happened before I won my Silver."

Maroney says Nassar gave her a sleeping pill on a flight to Tokyo when she was 15 -- "and the next thing I know, I was all alone with him in his hotel room getting a 'treatment.' I thought I was going to die that night."

McKayla joins a long list of women accusing Nassar of sexual misconduct -- 125 women, including former gymnasts, have already filed suit against him for alleged incidents over the years.
