Oprah: What was your reaction when you learned that USADA was going to pick up the case.
Armstrong: I felt like they were coming into my territory and I would fight back. If I could go back, I would not fight back, I wouldn't file a case. I would listen.
Armstrong: To go back to that moment, I would say give me three days, let me call my family, my mother, my sponsors, and tell them what I'm gonna do. I'm going to be right there (to testify.)
Oprah: You can't take that back but in the future, will you cooperate with USADA?
Armstrong: I disrespected the rules but if we can, and I stand on no moral platform here, but if they have it (an effort to clean up the sport) and I was invited, I would be the first man at the door.
Armstrong: George is the most credible voice in all of this. I don't fault George Hincapie. He knows the story better than anybody.
That's it for Part 1 of the Lance Armstrong interview on Oprah. It continues tomorrow at 10 am!
Part 2 of Oprah's interview with Lance Armstrong starts.
Oprah and Armstrong now talking about the Livestrong Foundation.
Oprah: Of everything that happened in this entire process, in this fall from grace, has this been the lowest (resigning as Livestrong chairman)?
Armstrong: Yes, this is the lowest.
Oprah: Are you facing your demons?
Armstrong: Absolutely. It's a process.
"Can Livestrong survive without you?" Armstrong: I hope so.
Oprah: Do you think that banned substances contributed to you getting cancer?
Armstrong: I don't think so. I'm not a doctor. I don't have a doctor suggest that to me personally.
Armstrong on what he thinks about himself back in 2005: I don't like that guy. He felt and believed he was invincible. He's still here, I'm not going to lie to the public. But his on the process of exiting.
Armstrong to his fans: I understand your anger. You supported me forever, and I lied to you. I'm sorry. I'm willing to spend as long as I have to to make amends.
"Do I want to compete again?" Armstrong: Hell yes. I'm a competitor. That's what I've been doing all my life.
Oprah: Do you owe David Walsh an apology who for 13 years pursued this story?
Armstrong: I'd apologize to David.
Armstrong on whether he is doing this interview because he wants to get back to cycling
: Hell yeah, I'm a competitor. I love to race.
"Do you think you deserved to be punished?" Armstrong: I deserve to be punished. I'm not sure that I deserve a death penalty.
Armstrong: I can't lie to you. I'd love the opportunity to be able to compete. This may not be the most popular answer but I think I deserve it.
Armstrong: I would I like to run the Chicago marathon when I'm 50, but I can't.
"Do you have remorse?" Armstrong: Everybody thinks its kind of bummed out they got caught. Do I have remorse? Absolutely. I'm paying the price but I deserve it.
Oprah (on Armstrong's tweets after he was stripped of his medal) : Was it just you being your jerky arrogant self? What was that?
Armstrong: That was just more defiance. And you know what's scary is I actually thought it was a good idea at the time.
Oprah: How has it changed the way you see yourself? Or has it?
Armstrong: Not completely. This is heavy. This is messy and this isn't something I can tell you that yeah, we're okay.
Armstrong says there were people who knew about the truth, and wanted him to stop the lying.
Oprah: Could they have done something? Armstrong: No.
Armstrong talks about his ex-wife Kristin: She believes the truth will set you free. We believed in a lot of different things, but that doesn't matter. We have three kids, they deserve the truth. They deserve an honest dad.
Oprah: Was there anybody who knew the whole truth? Armstrong: Yeah.
Armstrong says his ex-wife Kristin was the only person he asked on whether he could come back to cycling. Kristin said yes but on one condition -- that he would not dope anymore.
Lance talks about his 13-year-old son Luke: He never asked me "dad is this true?" He trusted me.
Armstrong on the verge of tears.
Armstrong on coming in 3rd place after his comeback: I didn't expect it. I just got beaten by two people who were just better than me. I did everything I could but I was beaten.
Armstrong on what he told his son Luke: I've always denied, which is probably why they trusted me. "I just want you to know their true. Don't defend me anymore"
Lance on his son Luke: He's been remarkably calm and cool about this.
Lance tells what his son Luke told him: Look, I love you. Your my dad. This won't change that.
Oprah: Did you expect defiance from your son Luke?
Lance: Thank God, he (Luke) is more like Kristin than like me.
Oprah: What was your intention that would come out of it (confession)?
Lance: I've suddenly lost all future income. You ask me about the cost? I don't like thinking about it.
Armstrong says he is doing this for his children. "This conversation will live forever. So I gotta get that right for them as they enter the dent of their lives."
Lance: I'm an optimist. I'm like my mom. I like to look forward. We don't talk about the past. I never asked about my biological father. How is she taking this? She's a wreck. She never told me, but my stepfather called. But she's a tough woman.
"Will you rise again?" Lance: I don't know. I don't know the outcome here but I'm getting comfortable with that. That would have driven me crazy, but I'm there. I'm sorry.
"Are you a better human being because this happened?" Lance: Without a doubt.
Lance: I can't lose myself again. I'm in no position to make promises, but that's the biggest challenge in my life - to not slip up again. I had it, and things got crazy. It's an epic challenge.
"What's the moral to this story?" Lance: I don't have a great answer to that. There's a lot of things that shouldn't be done. The ultimate crime is the betrayal of this people who supported me and believed in me.
Oprah: I think the moral of this story is what Kristin told you in 2009. "The truth will set you free."
