Ex-USADA chief says Armstrong rep offered payment - report

Former US Anti-Doping Agency chief Terry Madden told US media on Saturday that Lance Armstrong did offer USADA a donation in 2004, contrary to the shamed cyclist's claim in a confessional TV interview.

Armstrong's vehement denial of the claim made by current USADA Chief Executive Travis Tygart, came in the second installment of his pre-recorded interview with talk-show host Oprah Winfrey, which aired on Friday.

"This is another personal attack on Travis Tygart and the United States Anti-Doping Agency," Madden, chief executive of the agency from 2000-07, told the New York Daily News.
