Usada to Reveal Evidence Against Armstrong
The agency has banned the cyclist for life and stripped him of his Tour de France titles
The United States Anti-Doping Agency (Usada) is preparing to reveal its evidence against Lance Armstrong.
Usada has banned the American cyclist for life, stripping him of his record-breaking seven Tour de France titles.
The move followed Armstrong's refusal to answer charges that he was the "ring-leader" of a doping conspiracy.
Armstrong says he is innocent and that only the sport's governing body, the International Cycling Union (UCI), has the power to sanction him.
