AUSTIN, Texas (AP) — After a decade of denial, Lance Armstrong has finally come clean: He used performance-enhancing drugs to win the Tour de France.

The disgraced cyclist made the confession to Oprah Winfrey during an interview taped Monday, 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.

The admission Monday came hours after an emotional apology by Armstrong to the Livestrong charity that he founded and took global on the strength of his celebrity as a cancer survivor who came back to win one of sport’s most grueling events.
