He was almost as reluctant to discuss claims by former teammates Tyler Hamilton and Floyd Landis that Armstrong told them, separately, that he tested positive during the 2001 Tour de Suisse and conspired with officials of the International Cycling Union officials to cover it up — in exchange for a donation.
"That story wasn't true. There was no positive test, no paying off of the labs. There was no secret meeting with the lab director," he said.
Winfrey pressed him again, asking if the money he donated wasn't part of a tit-for-tat agreement, "Why make it?"
"Because they asked me to," Armstrong began.
"This is impossible for me to answer and have anybody believe it," he said. "It was not in exchange for any cover-up. ... I have every incentive here to tell you yes."
Finally, he summed up the entire episode this way: "I was retired. ... They needed money."
Ultimately, though, it was Landis who did the most damage to Armstrong's story. Landis was stripped of the 2006 Tour title after testing positive and wound up on the sport's fringes looking for work. Armstrong said his former teammate threatened to release potentially destructive videos if he wasn't given a spot on the team. That was in 2009, when Armstrong returned to the Tour after four years off.
Winfrey asked whether Landis' decision to talk was "the tipping point."
"I'd agree with that. I might back it up a little and talk about the comeback. I think the comeback didn't sit well with Floyd," Armstrong recalled.
"Do you regret now coming back?"
"I do. We wouldn't be sitting here if I didn't come back," he said.
