The USADA report said Armstrong and his teams used steroids, the blood booster EPO and blood transfusions. The report included statements from 11 former teammates who testified against Armstrong.
"I was sickened by what I read in the USADA report," McQuaid said, singling out the testimony of David Zabriskie. "The story he told of how he was coerced and to some extent forced into doping is just mind boggling."
Armstrong denies doping, saying he passed hundreds of drug tests. But he chose not to fight USADA in one of the agency's arbitration hearings, arguing the process was biased against him. Former Armstrong team director Johan Bruyneel is also facing doping charges, but he is challenging the USADA case in arbitration.
"I've been better, but I've also been worse," Armstrong, a cancer survivor, told the crowd.
