Armstrong said Wednesday, Oct. 17, 2012, he is stepping down as chairman of his Livestrong cancer-fighting charity so the group can focus on its mission instead of its founder's problems. The move came a week after the U.S. Anti-Doping Agency released a massive report detailing allegations of widespread doping by Armstrong and his teams when he won the Tour de France seven consecutive times from 1999 to 2005.
