te'o, the notre dame football player that was caught up in the love hoax. Sat down with katie for several hours. It will air this afternoon on "katie." And katie joins us now. What a conversation. It was interesting to talk to manti after all the coverage, all of the controversy. And prior to this interview, george, a lot of people tweeted me or facebooked me and said, please, ask him for his pho records. And, in fact, we did. And he showed them to us. And there were dozens of calls to this number, this number of so-called lennay, you know? And some of them lasted for hours on end. Even overnight. So, we talked about that. And here's what he had to say. I understand you would fall asleep holding the phone? Uh-huh. Reporter: Or with the phone next to you. Connected to this individual. And then, when you woke up, you would talk to this person. I hope you have rollover minutes, by the way. Mobile-to-mobile. Mobile-to-mobile. Reporter: But I mean, why would you do that? It goes back to what my parents taught me. Always be there for somebody when they need help. Reporter: She came out of her coma when she was on the phone with you, the phone was next to her. What did you hear on the other end of the line? Obviously, it was just breathing at first. It was one of those where she was just breathing. Then, she started to kind of whisper my name. And I'm -- I jumped for joy. She's out. She's talking. And I kind of -- I was a little pumped. They were right, I do help her. Reporter: Now, many people writing about this are calling your son a liar. They're saying he manipulated the truth, really for personal gain. People can speculate about what they've think he is. I've known him 21 years of his life. And he's not a liar. Just a kid. That was manti's father, brian te'o, along with his mom, who participated in the interview. The big question that everyone's been asking and accusing manti te'o of, is embellishing, and misleading and prolonging this story because it was part of his personal narrative. That's a big focus of our interview today. You also have some of the voicemails of the person who was calling him. We're learning from "the new york daily news" this morning, the voice on the phone is the man behind the whole hoax in a kind of falsetto. That is, in fact, his voice. And I talked to him about that during the course of the interview, george. I said, do you think he could have been playing the role of lennay? He said, it didn't sound like a man, it sounded like a woman. That's a talent to do it, every, single day. You heard the voicemails? We played the voicemails. And honestly, it sounds like a girl to me. Sounds like a girl? It does. But this ronaiah fellow is involved in music and audio. He writes songs. So, who knows what kind of equipment he had to enhance his voice or autotune it somehow. Today, we hear manti's side of the story. We'll hear the whole thing on "katie."
