LOS ANGELES: Disgraced cyclist Lance Armstrong will discuss the doping scandal that dramatically brought down his career during an interview with Oprah Winfrey next week.
The talkshow host said a 90-minute special program would address ''years of accusations of cheating, and charges of lying about the use of performance-enhancing drugs'' throughout Armstrong's ''storied cycling career''.
The interview will be Armstrong's first since being stripped of his seven Tour de France titles last year, and will air on the Oprah Winfrey Network. It will also be streamed live on her website, a statement said.
Last week, The New York Times reported that Armstrong, 41, was considering publicly admitting that he used banned performance-enhancing drugs, in an apparent bid to return to competitive sport in marathons and triathlons.
''Looking forward to this conversation with @lancearmstrong,'' Winfrey posted on her Twitter site on Tuesday. Armstrong retweeted the comment 15 minutes later.
In the interview, to be shown in a primetime slot next Thursday (Friday, January 18, Sydney time), Winfrey will speak with Armstrong at his home in Austin, Texas.
Armstrong has vehemently denied doping. It is not known if he will admit to doping on Winfrey's show. The show used words such as ''alleged doping scandal'', ''accusations of cheating'' and ''charges of lying'' in its publicity statement.
The announcement came on the same day that 60 Minutes said US Anti-Doping Agency chief executive Travis Tygart told it in an interview to be aired on Wednesday (Thursday Sydney time) that Armstrong attempted to donate about $US250,000 ($240,000) to the organisation.
Tygart said he was bowled over by the ''totally inappropriate'' donation offer from one of Armstrong's representatives in 2004, which he immediately refused.
''I was stunned,'' Tygart said in the interview. ''It was a clear conflict of interest for USADA. We had no hesitation in rejecting that offer.''
Asked if the offer was in the range of $US250,000, Tygart said: ''It was in that ballpark.''
Tygart, who described Armstrong's heavy-handed tactics as being similar to those of the mafia, denounced a $US100,000 donation Armstrong made previously to the International Cycling Union (UCI).
But Armstrong's lawyer, Tim Herman, told USA Today on Tuesday that there was never a donation attempt from the cyclist. ''No truth to that story,'' Herman told the newspaper. ''First Lance heard of it was today. He never made any such contribution or suggestion.''
USADA stripped Armstrong of his Tour de France titles and slapped him with a lifetime ban in October after releasing a damning report that said he helped orchestrate the most sophisticated doping program in the history of the sport.
The UCI effectively erased Armstrong from the cycling history books when it decided not to appeal sanctions imposed on Armstrong by USADA.
The report by USADA included hundreds of pages of witness testimony, emails, financial records and laboratory analysis of blood samples. ''We have an obligation to clean athletes and the future of the sport,'' Tygart said. ''This was a fight for the soul of the sport.''
US federal officials investigated Armstrong and his cycling team for two years but failed to charge him.
The decision not to charge Armstrong stunned Tygart. He was also upset when the US Justice Department refused to share the results of its probe with him.
Asked why he thought the Justice Department refused to bring charges, Tygart said: ''It's a good question, and one that if you finally answer, let me know.''
Tygart said Armstrong and his secretive inner circle of doctors, coaches and cyclists acted like the mafia the way they intimidated cyclists into using performance-enhancing drugs. ''It is our job … to protect clean athletes,'' Tygart said. ''There are victims of doping.''
Late last year, Armstrong, a cancer survivor, resigned as chairman of the Livestrong foundation he created.
