Lance Armstrong may have officially admitted to using performance-enhancing drugs to help him win cycling championships in an interview with Oprah Winfrey on Jan. 14.
The likely admission was taped and is slated to air on Winfrey's OWN network in a two-part special set to air on Thursday, Jan. 17 and Friday, Jan. 18.
Winfrey appeared on "CBS This Morning" on Jan. 15 to discuss her chat with Armstrong with her best friend, anchor Gayle King.
When asked if Armstrong admitted to using performance-enhancing drugs, she said while she "was satisfied" and "riveted by some of his answers, he didn't come clean in the manner I expected."
In her almost three hour chat with the Tour de France champ, she said he was "truthful, serious [and] certainly had prepared himself for this moment."
Winfrey prepared 112 questions for her time with Armstrong in Austin, Texas which she described as "the biggest interview (she) has ever done." She revealed she was so tough with her questioning that Armstrong asked her to "lighten up a bit." None of Armstrong's attorneys were in the room during the interview.
The media mogul shared that "there were times" when Armstrong was emotional during her questioning.
Winfrey said she didn't trust sending the interview electronically, so she carried the footage with her on tape personally for her flight back to Chicago.
She closed her CBS interview, sharing that at the end of their chat, both she and Armstrong were "exhausted" and "satisfied."
Winfrey caused speculation that Armstrong "came clean" when she tweeted on Jan. 14, "Just wrapped with @lancearmstrong More than 2 1/2 hours. He came READY!" after she met with him.
She sent the tweet several hours after Armstrong formally apologized to almost 100 employees at his former company, Livestrong Foundation. An insider told Fox News that he said "I'm sorry" in a twenty-minute conversation that left several staff members in tears. He apologized for the controversy, what he put them through and asked them to continue to focus on the non-profit's mission to get cancer patients and their families the assistance they need.
Armstrong was stripped of all seven of his Tour De France titles that he won between 1999 and 2005 after a U.S. Anti-Doping Agency report revealed details his doping program. USADA chief executive Travis Tygart reportedly described Armstrong's doping regimen as "the most sophisticated, professionalized and successful doping program that sport has ever seen."
