Livestrong, the cancer charity founded by disgraced cyclist Lance Armstrong, said on Thursday it was "disappointed" that he had misled it and many others about doping.
"We at the Livestrong Foundation are disappointed by the news that Lance Armstrong misled people during and after his cycling career, including us," it said after the broadcast of Armstrong's interview with Oprah Winfrey.
Armstrong, 41, used the interview to come clean for the first time about his use of performance enhancing drugs to win successive Tour de France races, after a decade of strident denials.
Prior to recording the interview on Monday in his hometown of Austin, Texas, he personally went to Livestrong headquarters to apologize to its staff -- and in the interview, he wore its iconic yellow rubber wristband.
"We accepted his apology in order to move on and chart a strong, independent course," the charity said in its statement, received 40 minutes after the conclusion of the first part of the broadcast that continues on Friday.
