USADA rejects WADA criticism of ‘undercover agents’ protected from doping sanctions

Travis Tygart, CEO of the US anti-doping agency (USADA), and principal player in the sanctions against Lance Armstrong, has issued a strong defence of the agency’s use of informants after vocal public criticism from WADA.

Key to WADA’s criticism was the claim that three US athletes were allowed to compete despite committing anti-doping violations, in exchange for information in a period between 2011 and 2014.
