FILE - In this Feb. 15, 2011 file photo, Lance Armstrong pauses during an interview in Austin, Texas. In 2012, Armstrong decided to give up the battle against doping charges, saying "enough is enough" but acknowledging no wrongdoing. The move began his swift fall from being perhaps the nation's best-known cancer-fighting hero, and though he maintains he was victimized by a "witch hunt" he was still stripped of all seven of his Tour de France victories.
