Armstrong has evidence against UCI: Usada chief
PARIS (AP) - The head of the United States Anti-Doping Agency (Usada) wants Lance Armstrong to come forward with information detailing the alleged complicity of cycling's governing body in his doping.
Mr Travis Tygart appeared at a French government hearing in Paris on Thursday to discuss ways to improve the fight against doping.
After the Usada's scathing report on systematic doping by Armstrong and his teams, he was stripped of his seven Tour de France titles and banned from elite sport for life.
Cycling body Union Cycliste Internationale (UCI) has been accused of covering up suspicious samples from Armstrong, accepting financial donations from him and helping him avoid detection in doping tests.
