With a day to go before the world learns exactly what Lance Armstrong said to Oprah Winfrey about his involvement in doping as a professional cyclist, the cancer charity he founded urged the fallen star to come clean.
"We expect Lance to be completely truthful and forthcoming in his interview and with all of us in the cancer community," Livestrong said in a statement released Wednesday. "We expect we will have more to say at that time."
The U.S. Anti-Doping Agency accused Armstrong in October of involvement in a sophisticated doping program while he was a professional cyclist. The world governing body for cycling, the International Cycling Union, stripped Armstrong of his seven Tour de France titles following the report. He's also been banned from the sport for life.
Speaking with her close friend Gayle King on "CBS This Morning" on Tuesday, Winfrey appeared to confirm media reports that the former Tour de France champion acknowledged to her that he had used performance-enhancing substances.
Winfrey's 2½-hour interview with Armstrong is to be aired Thursday and Friday on Winfrey's OWN cable network and on the Internet.
If true, such an admission would be a stunning reversal after years of vigorous denials, including lawsuits filed against accusers.
But it still will not be enough to reverse the lifetime ban and other sanctions that have kept him from participating in some triathlons -- the three-event sport he took up after retiring from cycling.
"Only when Mr. Armstrong makes a full confession under oath -- and tells the anti-doping authorities all he knows about doping activities -- can any legal and proper process for him to seek any reopening or reconsideration of his lifetime ban commence," said David Howman, director general of the World Anti-Doping Agency.
Winfrey said her team and Armstrong's camp had originally agreed not to leak details of the interview, and that she was surprised to find that not long after the interview, news reports were saying part of what Armstrong told her had "already been confirmed."
Winfrey declined to characterize Armstrong's answers or offer preview quotes, but said Armstrong came ready.
