NEW YORK (AP) - Doping charges continue to dog seven-time Tour de France champion Lance Armstrong.
The latest allegation comes from Tyler Hamilton, a former teammate who told "60 Minutes" that he used performance-enhancing drugs with Armstrong to cheat in cycling races, including the tour.
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. EPO is a drug that boosts endurance by increasing the number of red blood cells in the body.
Armstrong's attorney Mark Fabiani says Hamilton "just duped" "60 Minutes" and is only out to make money writing a tell-all book. 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.
