Lance Armstrong admits to doping during Oprah interview (UPDATE)

Lance Armstrong has admitted to doping during his interview Monday evening with Oprah Winfrey, a person familiar with the situation told The Associated Press. 

Armstrong's entourage was seen leaving the downtown Austin hotel where the interview took place, including the cyclist's attorneys Tim Herman and Sean Breen, as well as his agent and manager Bill Stapleton.

None of them commented on the interview, according to the AP. 

His meeting with Winfrey Monday is the first time the athlete comments on the doping allegations brought against him in a report by the US Anti-Doping Agency, the Washington Post reported. 

Oprah tweeted afterwards: 

The disgraced cyclist, who had his seven Tour de France titles stripped in the wake of his doping scandal, also apologized to his Livestrong staff on Monday in advance of his meeting with Oprah.

He addressed about 100 staffers at the organization's Austin headquarters. Spokeswoman Katherine McLane said that his "sincere and heartfelt apology" brought many to tears, and that Armstrong "took responsibility" for the issues he created for the foundation, ABC News reported.  

"I'm calm, I'm at ease and ready to speak candidly," Armstrong had told the Associated Press Sunday.  

The discussion was originally set to take place at his home, but the location reportedly changed to the Austin hotel Monday afternoon, ESPN reported. 

The edited 90-minute interview is scheduled to air on the Oprah Winfrey Network on Thursday.
