New York, NY (Sports Network) - Lance Armstrong spoke with Oprah Winfrey on Monday and apparently told her that he did use performance-enhancing drugs during his cycling career.
Winfrey met with Armstrong for about 2 1/2 hours in his hometown of Austin, Texas.
Details were not provided after the interview, but Winfrey spoke Tuesday on the program "CBS This Morning" and didn't refute reports from Monday night that the seven-time Tour de France winner confessed in some form.
"I would say he did not come clean in the manner I expected," Winfrey told the CBS program. "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 she had prepared 112 questions, although she didn't get to ask all of them, and said he "answered the questions in a way that he was ready."
The Armstrong interview was scheduled to be broadcast Thursday on the Oprah Winfrey Network, but Winfrey said it will now air over two nights -- Thursday and Friday -- because of the length.
Armstrong won the Tour de France, cycling's most famous race, from 1999-2005, but was stripped of all seven titles in October of 2012 following a lengthy investigation by the United States Anti-Doping Agency.
USADA accused Armstrong of using, attempting to use or possessing EPO, blood transfusions, testosterone, corticosteroids and masking agents, and said blood samples from 2009 and '10 showed data that was "fully consistent with blood manipulation including EPO use and/or blood transfusions."
The 41-year-old cancer survivor, who adamantly denied doping for years, was issued a lifetime ban from cycling amid USADA's findings, causing him to be dropped by multiple sponsors and forcing him to step down from Livestrong, the cancer-fighting charity he founded.
Reports also indicated that Armstrong apologized to members of the Livestrong Foundation on Monday.
