Armstrong Confesses Doping to Oprah

Interview to be aired Thursday

AUSTIN, Texas—Lance Armstrong confessed to Oprah Winfrey during an interview Monday that he used performance-enhancing drugs to win the Tour de France, a person familiar with the situation told The Associated Press.

The person spoke on condition of anonymity because the interview is to be broadcast Thursday on Winfrey's network.

Armstrong was stripped of all seven Tour titles last year following a voluminous U.S. Anti-Doping Agency report that portrayed him as a ruthless competitor, willing to go to any lengths to win the prestigious race.
