COLORADO SPRINGS, Colo. -- The chief of the U.S. Anti-Doping Agency tells "60 Minutes Sports" that a representative for Lance Armstrong offered the agency a "donation" in excess of $150,000 several years before a USADA investigation led to Armstrong being stripped of seven Tour de France titles.
In an interview on the show's premiere airing on Showtime Wednesday night, USADA CEO Travis Tygart said he was "stunned" when he received the offer in 2004.
"It was a clear conflict of interest for USADA," Tygart said. "We had no hesitation in rejecting that offer."
Armstrong's attorney, Tim Herman, denied such an offer was made.
"No truth to that story," Herman wrote Tuesday in an email to The Associated Press. "First Lance heard of it was today. He never made any such contribution or suggestion."
Tygart was traveling and did not respond to requests from the AP for comment. USADA spokeswoman Annie Skinner said Tygart's comments from the interview were accurate. In it, he reiterates what he told the AP last fall: That he was surprised when federal investigators abruptly shut down their two-year probe into Armstrong and his business dealings, then refused to share any of the evidence they had gathered.
"You'll have to ask the feds why they shut down," Tygart told the AP. "They enforce federal criminal laws. We enforce sports anti-doping violations. They're totally separate. We've done our job."
