Béla and Márta Károlyi say they did not know about Larry Nassar assault

Béla and Márta Károlyi, the former USA Gymnastics national team coordinators and owners of the USA Gymnastics National Team Training Center at Károlyi Ranch in Huntsville, Texas, have finally spoken out about the Larry Nassar sexual assault scandal.

Both Béla and Márta Károlyi, who have been named as co-defendants in several civil lawsuits that have been filed against Nassar and USA Gymnastics, claim that they did not know that Nassar was sexually assaulting gymnasts at Károlyi Ranch.

Here is what Béla Károlyi had to say about the situation, according to ESPN.

"The whole thing is just like an explosion, a bomb exploding."

Here is what Márta Károlyi had to say about the situation, according to ESPN.

"The whole gymnastics community couldn't recognize this. Everybody said, 'Larry Nassar is a good doctor. Larry Nassar is a good guy.' 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?"

Here is a video of Béla and Márta Károlyi finally breaking their silence on the scandal in an interview with TODAY's Savannah Guthrie.

The full interview with Béla and Márta Károlyi is set to air on an hourlong Dateline NBC special called "Silent No More" on Sunday, April 22 at 7:00 pm ET.

This feature is also set to feature an interview with former Olympic gymnast McKayla Maroney, who spoke publicly about the sexual assault that she was forced to endure at the hands of Nassar for the first time just this past week.

Maroney, along with three of her teammates from the United States Olympic women's gymnastics team in the 2012 Summer Olympics in London, England, including Aly Raisman, Gabby Douglas and Jordyn Wieber, have accused Nassar of sexual assault and finally helped bring him to justice.

Nassar was finally arrested in December of 2016 after roughly two decades of sexually assaulting at least 260 individuals, many of whom female gymnasts, under the guise of medical treatment.

Nassar was sentenced to 60 years in federal prison this past December on three child pornography charges. In January, he was sentenced to between 40 and 175 years in state prison on seven sexual assault charges, and in February, he was sentenced to between an additional 40 and 125 years in state prison on three more sexual assault charges.

He is currently serving his 60-year federal prison sentenced at United States Penitentiary Tucson, which is a maximum-security federal prison in Tucson, Arizona that offers a sex offender program for sexual predators such as Nassar.
