While sharing a preview of the interview, Sawyer said that she gave Jenner some time to speak openly.

"I think we can all agree that some stories can only be told by the person who lives them," Sawyer said.

Jenner's interview will be a story of family love, she said. The reality television star and former Olympian has six biological children and four step-children. Jenner and the Kardashian family are the stars of the reality TV show "Keeping Up With the Kardashians."

"Those are the only ones I'm concerned with," Jenner said about the family. "I can't let myself hurt them."
