Lance Armstrong and other team leaders encouraged, promoted and took part in a doping program in an effort to win the Tour de France in 1999 and beyond, former teammate Tyler Hamilton said during a report aired Sunday on 60 Minutes.
Hamilton said he saw Armstrong take performance-enhancing drugs, EPO and testosterone and saw him receive a banned blood transfusion in 2000.
"I feel bad that I had to go here and do this," Hamilton said in his first public admission of doping. "But I think at the end of the day, like I said, long term, the sport's going to be better for it."
Team leaders, including doctors and managers, encouraged and supervised doping, Hamilton said.
Armstrong, who won the Tour each year from 1999 to 2005, has denied doping and has never tested positive.
On Sunday, his attorney, Mark Fabiani, released a statement deriding the CBS report.
"Throughout this entire process, CBS has demonstrated a serious lack of journalistic fairness and has elevated sensationalism over responsibility," Fabiani said. "CBS chose to rely on dubious sources while completely ignoring Lance's nearly 500 clean tests and the hundreds of former teammates and competitors who would have spoken about his work ethic and talent."
