Editor's note: Don't miss Betsy Andreu live on AC360° at 10 p.m. ET tonight after the conclusion of Part II of Lance Armstrong's interview.
Betsy Andreu, wife of Lance Armstrongs former teammate Frankie Andreu, reacts immediately after seeing Armstrong's interview with Oprah. She says she is disappointed and furious that he didn't tell the truth.
"You owed it to me Lance, and you dropped the ball. After what you've done to me, what you've done to my family, and you couldn't own up to it. And now we're supposed to believe you? You have one chance at the truth. This is it," said Andreu.
She told Anderson Cooper what angered her most about the interview was his refusal to admit she and her husband were telling the truth about overhearing him tell doctors he was using performance-enhancing drugs in 1996. The couple testified about the incident in 2005.
Daniel Coyle, Roger Cossack and Juliet Macur discuss the risks and motivation behind Lance Armstrong talking to Oprah.
"This is a perfect lens into the way Lance's brain works," says Coyle. "He's really good at figuring out complex situations...at this point he figured the best path forward was to go to Oprah."
If Armstrong does admit to cheating in the interview, why was he compelled to come forward now? He's spent years aggressively denying accusations, and he could have avoided being banished for life when the USADA invited him to confess and help restore the integrity of the sport.
Macur says it boils down to what has always been his main focus: competing. She points out, "the difference between several months ago and now is that he's had several months of no competition, and for a guy like Lance Armstrong, that must be torture."
Betsy Andreu, the wife of one of Lance Armstrong's former teammates, says Armstrong bullied her family after she testified against him. New York Times sports reporter Juliet Macur talks about Armstrong's history of intimidation and the athlete's loyal following.
Tyler Hamilton claims his former teammate Lance Armstrong, and others, used back-dated prescriptions to cover for doping. He says the International Cycling Union knew about it and looked the other way.
The cycling career of Lance Armstrong was "fueled from start to finish by doping," according to a scathing 202-page report from the U.S. Anti-Doping Agency detailing allegations against the seven-time Tour de France winner. The USADA says the path Armstrong took to win "ran far outside the rules."
Eleven of Armstrong's former teammates testified in the investigation, including Tyler Hamilton, who talks with Anderson tonight about the report in an AC360 exclusive interview. According to the report, Hamilton told investigators he and his teammates hid from drug testers.
Watch the preview clip above of Anderson's conversation with Hamilton, who rode with Armstrong on the U.S. Postal Service team from 1998 to 2001.
The cycling team used a wide range of techniques, including saline injections and blood transfusions, to beat those tests, according to the USADA report. Armstrong and his former teammates "ran the most sophisticated, professionalized and successful doping program that sport has ever seen," claims the USADA.
The U.S. Anti-Doping Agency today slapped Lance Armstrong with a life-time ban and said the superstar cyclist will be stripped of his seven Tour de France titles, after Armstrong announced he's giving up his battle to clear his name of doping charges.
Armstrong maintains he's innocent, that he's never used performance enhancing drugs, and that he's never once tested positive.
So why then is he giving up the fight to clear his name and save his legacy?
Bill Strickland, editor-at-large at “Bicycling” magazine, has followed Armstrong's career from the beginning. He shares his take with Anderson.
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
