Lance Armstrong, seven-time Tour de France winner, vehemently denied bold accusations by former Olympic champion and former teammate Tyler Hamilton regarding usage of performance enhancing drugs.

Following the accusations, Mark Fabiani, Armstrong's spokeman said, Hamilton just duped the CBS Evening News, 60 Minutes and Scott Pelley all in one fell swoop.

He continued, Hamilton is actively seeking to make money by writing a book, and now he has completely changed the story he has always told before so that he could get himself on 60 Minutes and increase his chances with publishers.

Greed and a hunger for publicity cannot change the facts: Lance Armstrong is the most tested athlete in the history of sports. He has passed nearly 500 tests over 20 years of competition.

Hamilton told 60 Minutes correspondent Scott Pelley, I saw (EPO) in his refrigerator. I saw him inject it more than one time, like we all did, like I did many, many times.

Hamilton joins a litany of Armstrong accusers including Floyd Landis, also a former teammate.

A federal investigation on systematic doping is currently being conducted on Armstrong and the former U.S. Postal team.
