Lance Armstrong doping case

The Lance Armstrong doping case was a doping investigation that led to Lance Armstrong being stripped of his seven Tour de France titles and his eventual admission to the doping.

For much of his career, Lance Armstrong faced persistent allegations of doping, but until 2006 no official investigation was undertaken. The first break in the case came in 2004, when SCA Promotions, a Dallas-based insurer, balked at paying a $5 million bonus to Armstrong for winning his sixth consecutive Tour. SCA president Bob Hamman had read L.A. Confidentiel, a book by cycling journalists Pierre Ballester and David Walsh which detailed circumstantial evidence of massive doping by Armstrong and members of his U.S. Postal Service Pro Cycling Team. In 2006, an arbitration panel ruled that SCA had to pay. However, Hamman's real goal was to force an investigation by sporting authorities. His hunch proved correct; officials from the United States Anti-Doping Agency (USADA) asked to review the evidence Hamman had gleaned.

U.S. federal prosecutors pursued allegations of doping by Armstrong from 2010 to 2012. The effort convened a grand jury to investigate doping charges, including taking statements under oath from Armstrong's former team members and other associates; met with officials from France, Belgium, Spain, and Italy; and requested samples from the French anti-doping agency. The investigation was led by federal agent Jeff Novitzky, who also investigated suspicions of steroid use by baseball players Barry Bonds and Roger Clemens.

Armstrong's former teammate Floyd Landis was a key witness in the criminal investigation, and according to the book Wheelmen, Landis at one point wore a recording device and used a video camera disguised as a keychain, at the investigators' request in an attempt to gather evidence against a team owner in California. However, based on testimony from Landis, the prosecutors soon turned their attention to Armstrong and the doping that took place on the U.S. Postal Service team years earlier.
