Armstrong confessed to doping during an interview with Oprah Winfrey taped Monday, just a couple of hours after a wrenching apology to staff at the Livestrong charity he founded and has now been forced to surrender.

The day ended with 2 1/2 hours of questions from Winfrey at a downtown Austin hotel, where she said the world's most famous cyclist was "forthcoming" as she asked him in detail about doping allegations that followed him throughout his seven Tour de France victories.
