Oprah Winfrey did the marketing push for her interview with Lance Armstrong (OWN, Thursday, 9 p.m. ET).

Winfrey appeared on CBS This Morning, providing a tease of what’s in store for what now will be two shows with the disgraced biker. From USA Today:

“A couple of times he was emotional. ‘Emotional’ doesn’t begin to describe the intensity or difficulty (for Armstrong) in talking about these things. All these people wondering if he goes there and answers things … I think you will come away, too, that he brought it. He really did.”

And:

She told CBS she got to ask most of her “112” questions. “I would say he did not come clean in the manner I expected,” Winfrey said. “It was surprising to me … for myself, my team, all of us in the room, We were mesmerized and riveted by some of his answers.”

Winfrey said in addressing her questions, Armstrong answered “in a way (that showed) he was ready. … I can only say I was satisfied by the answers.”

Winfrey called it her “biggest interview”, which just might be hype given the people she’s interviewed through the years.

Beyond that, she said she chooses not to “categorize” how Armstrong comes off: “I would rather people make their own decisions. I felt he was thoughtful, he was serious, that he certainly had prepared himself for this moment. I would say he met the moment. At the end of it, we both were pretty exhausted.”

Why did she think Armstrong chose now to talk? “I just think the velocity of everything coming at him in the past couple of weeks, he was just ready.”
