US Anti-Doping Chief Unaware Of Americans In Damaging Report

WASHINGTON (Reuters) - A "thorough and aggressive review" needs to be done to protect clean athletes from "gangsters" after a blockbuster report surfaced alleging widespread doping in athletics, the head of the U.S. Anti-Doping Agency (USADA) said on Sunday.

Britain's Sunday Times newspaper and Germany's ARD/WDR broadcaster said they had obtained the secret data from the global athletics governing body, the IAAF, showing that endurance runners suspected of doping have been winning a third of Olympic and world championship medals.
