Bela, Martha Karolyi Deny Knowledge of Larry Nassar Abuse at Training Ranch

Former United States Gymnastics national team coordinators and coaches Martha and Bela Karolyi said in a recent interview that they had no knowledge of former USA Gymnastics physician Larry Nassar sexually abusing gymnasts at their training facility.

Speaking to NBC's Savannah Guthrie for a Dateline NBC special that will air Sunday, Martha said she in "no way" suspected Nassar of misconduct while working at the Karolyi Ranch, according to ESPN.com.

Former Olympic gymnast McKayla Maroney is among those who said they were abused by Nassar at the ranch, which is near Houston.

In separate cases, Nassar was sentenced to 40 to 175 years and 40 to 125 years in prison in January and February, respectively, on multiple counts of sexual abuse against girls and young women. He was also sentenced to 60 years in federal prison for possession of child pornography in December.

Nassar sexually assaulted patients under the guise of medical treatment, but Martha said she never witnessed it occurring at the Karolyi Ranch: "I heard during the testimonies that some of the parents were in the therapy room with their own child and Larry Nassar was performing this—and the parent couldn't see. How could I see?"

Per ESPN.com, the Karolyis are listed as defendants in multiple civil lawsuits against Nassar and USA Gymnastics.

Aly Raisman, Gabby Douglas, Simone Biles and Jordyn Wieber are among the high-profile gymnasts who have come forward as victims of Nassar's abuse alongside Maroney.

Martha helped assemble arguably the two best United States women's gymnastics teams of all time at the 2012 and 2016 Summer Olympics as national team coordinator and coach.

Team USA won team gold at both Games, and Karolyi retired from her coaching role in 2016 after the Rio de Janeiro Olympics.
