"I would say he did not come clean in the manner that I expected," says Oprah in this video clip. "It was surprising to me... All of us in the room, we were mesmerized and riveted by some of his answers... I had prepared and prepared like it was a college exam, and walked into the room with 112 questions. And in a two and a half hour interview, I asked as many of those questions as I could."

Lance Armstrong and Oprah talked on Monday, January 14 at a hotel near Armstrong’s home in Austin, Texas. During the conversation, which is Armstrong's first since being stripped of his Tour de France titles, he addressed the alleged doping scandal, years of accusations of cheating and use of performance-enhancing drugs throughout his career.

Immediately after the interview ended, Oprah shared her initial thoughts on Twitter: "Just wrapped with @lancearmstrong More than 2 1/2 hours. He came READY!"
