TX Mayor: Dems Who Boycotted Meeting With Trump 'Missed an Opportunity'

1996 Olympic gold medalist Dominique Moceanu joined Martha MacCallum on "The Story" on Friday to discuss the USA Gymnastics abuse scandal.

Disgraced former team doctor Larry Nassar was sentenced Wednesday to 40 to 175 years in prison for sexually assaulting more than 100 young female athletes.

Moceanu was not one of Nassar's victims, but she said she experienced rampant physical and emotional abuse during her time with USA Gymnastics.

She explained that she trained for the 1996 Olympics at the Karolyi Ranch in Huntsville, Texas, which was run by her former coaches, Martha and Bela Karolyi.

"That place holds some of my darkest memories in the sport, unfortunately," Moceanu said, describing constant intimidation, psychological abuse, body-shaming and "just cruelty."

She said that the Karolyis would portray a facade of loving, caring coaches in the media, but it was a very different story behind closed doors.

MacCallum asked Moceanu if she believes the Karolyis knew about the heinous crimes Nassar was committing at their training facility.

"The Karolyis knew how much we ate, they knew how much we weighed, they knew when we trained, they knew who they wanted on the World and Olympic teams," Moceanu said. "To say that they didn't know absolutely anything is questionable. ... And it needs to be investigated."

She argued that USA Gymnastics was susceptible to a predator like Nassar because of a "culture of psychological abuse."

"And it allowed the most prolific pedophile in our history -- and maybe in all of history, just for the sheer countless number of victims -- [to] walk through the walls of the sport."
