Floyd Landis, in his first television interview since admitting that he had used performance-enhancing drugs during his cycling career, has once again accused Lance Armstrong of cheating during Armstrong's record-setting career.
Landis, in an interview on ABC's "Nightline" on Friday night, said Armstrong -- his former teammate and friend -- transfused his own blood, a banned practice that gives athletes an advantage by increasing their red blood-cell count and, therefore, their endurance.
"Rather than go into the entire detail of every single time I've seen it, yes," Landis told Neal Karlinsky of "Nightline." "I saw Lance Armstrong using drugs."
Landis also said that Armstrong gave him testosterone patches -- a charge he has made before -- and that he saw Armstrong receiving blood transfusions during races.
Armstrong's lawyer, Tim Herman, denied the allegations.
"Landis is a confessed perjurer and he is a liar, and I think, as Lance said ... when you taste milk to see if it's sour, you take a first taste and you don't have to drink the whole carton to know it's all sour," Herman said.
Landis first admitted he had used performance-enhancing drugs in a series of e-mails to cycling and anti-doping officials implicating dozens of other athletes including Armstrong, team management and owners, and officials of the sport's national and international governing bodies.
He told ESPN.com's Bonnie D. Ford that "I don't feel guilty at all about having doped. I did what I did because that's what we [cyclists] did and it was a choice I had to make after 10 years or 12 years of hard work to get there, and that was a decision I had to make to make the next step. My choices were, do it and see if I can win, or don't do it and I tell people I just don't want to do that, and I decided to do it."
Landis was asked during the interview if he considers Armstrong a "fraud."
"Well, it depends on what your definition of fraud is," Landis said. "I mean it -- look -- if he didn't win the Tour, someone else that was doped would have won the Tour. In every single one of those Tours."
Armstrong is currently riding in the Tour de France, which concludes on Sunday. He has won the event seven times, but is back in the pack heading into the final weekend of this year's event.
