The FDA’s investigation, directed by agent Jeff Novitzky, is focused on whether Armstrong was involved in an organized doping operation as a member of the team sponsored by the U.S. Postal Service (USPS), an independent agency of the federal government. In light of this criminal inquiry involving the greatest Tour de France rider of all time, SI reviewed hundreds of pages of documents and interviewed dozens of sources in Europe, New Zealand and the U.S. Because the case could potentially involve accusations that are more than a decade old, SI also examined doping allegations against Armstrong throughout his career as a pro cyclist, discovering information that is reported here for the first time.
