>>> we're now learning more about the u.s. anti-doping agency's case against lance armstrong that led to the seven-time tour de france winner's life-time ban from the sport. he's denied cheating and long asked for proof. and now the agency is providing it. nbc's mike taibbi has more on this.
>> good morning, matt. in no less than 1,000 pages of evidence and testimony, including lab tests and sworn statements by armstrong 's teammates, the icon is painted as a user and supplier for the team of performance-enhancing drugs. also described as the leader of what the usda calls the most sophisticated and professionalized doping program in recent sports history . from 1999 on, lance armstrong won seven straight tour de france titles. he'd risen from the pinnacle from the death rattle of cancer. it made armstrong among the most recognizable, influential, and wealthy athletes in the world. but the usada says championships he collected while running with the u.s. postal service team were won by cheating.
>> he was the leader on the team. the team built its success, doping and otherwise, around him, to ensure he won those tour de frances.
>> the agency says retesting of blood samples taken as far back from 1999 showed a clear finding of epo. 11 of his teammates testified, several saying in sworn states they had direct knowledge that armstrong used drugs of said he gave them drugs. armstrong 's best friend on the team said he was aware that lance was using testosterone, epo, and blood transfusions . and tyler hamilton told matt on "today" what he told the agency, that are armstrong once paid his way out of a positive drug test .
>> it's the truth. it's the truth.
>> reporter: armstrong has denied doping allegations for years, even addressing the subject in one of his commercials for nike.
>> everybody wants to know what i'm on. what am i on? i'm on my bike six hours a day. what are you on?
>> reporter: but armstrong declined to challenge the agency's findings and says he will no longer address this issue regardless of the circumstances. his live strong charity, which has raised nearly $500 million for cancer research hasn't suffered so far.
>> we've raised two times what is normal.
>> reporter: and speaking of an era in pro cycling, when almost every top rider has admitted or suspected of cheating, armstrong 's lawyer said all of armstrong 's accusers would agree on one thing.
>> that armstrong was the best, the most talented, the most gifted, the hardest working, and the most focused rider who on a level playing field would've won everything that he won.
>> and what has armstrong lost? well, the chance to race again competitively, perhaps millions in prize money that he's won, and for many, a good part of his gold-plated reputation. but he still has the live strong charity in support of so many who see him as a leader in the fight against cancer. in fact, late wednesday, he tweeted to his millions of followers, what am i doing tonight? hanging with my family unaffected and thinking about this. and he linked to the live strong site. matt?
>> mike, thank you very much.
