AUSTIN, Texas (AP) -- Lance Armstrong's cycling career is behind him. Now he says the doping questions should go away as well.
Armstrong says he's done talking about doping rumors and allegations that dogged his seven Tour de France titles, after a nearly two-year federal investigation that closed with no charges being filed against him.
In recent interviews with Men's Journal and the "Gavin Newsom Show" on Current TV, Armstrong said he's "done" with the performance-enhancing drug question.
Armstrong, who has always denied doping, pointed to "500 to 600" negative drug tests in his career.
