Former USA Gymnastics women's national team coordinator Martha Karolyi and husband Bela told NBC they were unaware of the abusive behavior by a former national team doctor now serving decades in prison.
Martha Karolyi led the national team for 15 years before retiring after the 2016 Rio Olympics. She told reporter Savannah Guthrie in "no way" did she suspect Larry Nassar was sexually abusing athletes under the guise of treatment.
"The whole gymnastics community couldn't recognize this," Martha Karolyi said in an excerpt provided to The Associated Press on Friday by NBC. "Everybody said, 'Larry Nassar is a good doctor. Larry Nassar is a good guy.'"
The Karolyis spoke as part of a Dateline NBC special entitled "Silent No More" scheduled to air Sunday. The one-hour special, the first prime-time event hosted by Guthrie, takes a look at the fallout from revelations about years of abuse by Nassar involving hundreds of former athletes, including several members of the U.S. Olympic team.
"The whole thing is just like an explosion, a bomb exploding," Bela Karolyi said. "Boom."
The Karolyis have been named as co-defendants in several civil lawsuits filed against Nassar and Indianapolis-based USA Gymnastics. Several victims, including two-time Olympic medalist McKayla Maroney, say they were abused at the Karolyi's Ranch near Houston. The ranch served as the training home for USA Gymnastics during most of Martha Karolyi's highly successful tenure running the national team.
Guthrie spent hours with the Karolyis at the ranch after the couple agreed to speak publicly for the first time since Martha Karolyi's retirement following the 2016 Olympics.
"I think they felt like it was time for them to tell their side of the story," Guthrie said. "I think they've watched and seen as their reputation has really taken a hit and people have asked a lot of questions about what they knew and just as importantly what they should have known."
Guthrie said she was "surprised" the Karolyis came forward despite the potential legal fallout.
"They answered every question," Guthrie said. "At no time did their lawyer jump in and say 'You can't answer that.'"
Nassar spent nearly three decades at USA Gymnastics before being fired in 2015 after complaints about his behavior. He continued to work at Michigan State University through the fall of 2016 before being hit with federal charges. Nassar is now serving decades in prison for molesting women and girls and for possessing child pornography.
Nassar was already established in the program when Martha Karolyi took over. He would visit the ranch during national team training sessions and also accompany the team to events around the world. Maroney said she was abused "hundreds" of times by Nassar.
Martha Karolyi denied having any knowledge about Nassar's pattern of abuse.
"I heard during the testimonies (at Nassar's sentencing) that some of the parents were in the therapy room with their own child and Larry Nassar was performing this," Martha Karolyi told Guthrie. "And the parent couldn't see. How I could see?"
