On CBS This Morning moments ago, Oprah Winfrey confirmed that Lance Armstrong admitted to her in an interview recorded Monday that he did use performance-enhancing drugs during a cycling career that included seven Tour de France victories (titles he has since been stripped of).

The confession follows years of denials by the cycling superstar, who anti-doping authorities say was at the center of a vast and sophisticated network that supplied him with the drugs.

The 2 1/2 hour interview will now air on the Oprah Winfrey Network over two nights, Oprah told CBS, starting at 9 p.m. ET Thursday and continuing on Friday. It will also be streamed on Oprah.com.  More at NPR News
