NEW YORK — A former teammate of Lance Armstrong has told CBS News that he used performance-enhancing drugs with the seven-time Tour de France winner to cheat in cycling races, including the tour.
Tyler Hamilton says Armstrong took a blood-booster called EPO in the 1999 Tour and before the race in 2000 and 2001. Armstrong won the race every year from 1999-2005.
Armstrong has steadfastly denied doping and has never failed a drug test.
Federal investigators are probing whether Armstrong and his former U.S. Postal team engaged in a systematic doping program, which he denies.
