A televised confession by Lance Armstrong isn't enough.

Anti-doping officials want the disgraced cyclist to admit his guilt under oath before considering whether to lift a lifetime ban clouding his future as a competitive athlete. That was seconded by at least one former teammate whom Armstrong pushed aside on his way to the top of the Tour de France podium.

"Lance knows everything that happened," Frankie Andreu told The Associated Press on Tuesday. "He's the one who knows who did what because he was the ringleader. It's up to him how much he wants to expose."

Armstrong has been in conversations with U.S. Anti-Doping Agency officials, touching off speculation that he may be willing to cooperate with authorities there and name names.

Interviewer Oprah Winfrey didn't say if the subject was broached during the taping Monday at a downtown Austin hotel. In an appearance on "CBS This Morning," she declined to give details of what Armstrong told her, but said she was "mesmerized and riveted by some of his answers."

Winfrey was promoting what has become a two-part special, Thursday and Friday, on her OWN network.

Around the same time, World Anti-Doping Agency officials issued a statement saying nothing short of "a full confession under oath" would cause them to reconsider Armstrong's lifetime ban.
