Lance Armstrong Doping Investigation On '60 Minutes' (VIDEO)

According to a “60 Minutes” report, Lance Armstrong’s former teammates have admitted to federal authorities that not only did they use banned substances, but Lance Armstrong did as well.

An investigation by Scott Pelley’s team on “60 Minutes” into Armstrong and the use of banned substances in pro-cycling aired this Sunday.

The Associated Press reports on former teammate Tyler Hamilton's observations to "60 Minutes" regarding the U.S. Postal team operation:

-Team leaders, including doctors and managers, encouraged and supervised doping;

-Doping was going on inside the U.S. Postal team even before Armstrong joined in 1998;

-Performance-enhancing drugs, including EPO and human growth hormone, were handed out to cyclists in white lunch bags;

-Team members were met at the airport, driven to hotels, told to lie down and give blood that could be transfused back into their bodies at a later date.

Armstrong continues to deny doping. Armstrong’s attorney, Mark Fabian, has released multiple statements against the CBS report, remarking that Lance Armstrong “has passed nearly 500 tests over twenty years of competition.”

Regarding Hamilton, Fabian writes, “Tyler Hamilton is a confessed liar in search of a book deal – and he managed to dupe 60 Minutes, the CBS Evening News, and new anchor Scott Pelley. Most people, though, will see this for exactly what it is: More washed-up cyclists talking trash for cash.”

Tyler Hamilton has turned in his cycling gold medal to the U.S. Anti-Doping Agency.

As for George Hincapie, a teammate and close friend who "60 Minutes" reports testified to the grand jury about Armstrong’s involvement with EPO, Fabian writes, “In its unpardonable zeal to smear Lance Armstrong, CBS has also attacked the reputation of George Hincapie. We are confident that the statements attributed to Hincapie are inaccurate and that the reports of his testimony are unreliable. George Hincapie and his counsel have publicly said that they did not reveal any aspects of his testimony.”
