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.

Cyclist Lance Armstrong admitted to doping during an interview with Oprah Winfrey on Monday, the talk-show host said Tuesday. Winfrey said, “We were mesmerized and riveted” by Armstrong’s answers. “He did not come clean in the manner I was expecting.” Armstrong reportedly plans to testify against cycling officials who allegedly knew about his drug use. Armstrong also is believed to have issued a mea culpa to the staff of his charity, Livestrong, and called members of the cycling community to apologize for allegedly lying and misleading them. Winfrey also announced the interview had been spread over two nights, and will now air Thursday and Friday.
