Federal prosecutors dropped their investigation of champion cyclist Lance Armstrong Friday, ending a nearly two-year effort over whether Armstrong and his teammates cheated by doping during his greatest years. "I am gratified to learn that the U.S. Attorney's Office is closinga its investigation," Armstrong said. "It is the right decision and I commend them for reaching it. I look forward to continuing my life as a father, a competitor, and an advocate in the fight against cancer without this distraction."
