WASHINGTON The U.S. Anti-Doping Agency (USADA) has brought formal doping charges against U.S. cyclist Lance Armstrong and he has been immediately banned from competition in triathlons as a result, the Washington Post reported on Wednesday.
Armstrong, a seven-time Tour de France winner, denied the charges in a statement: "I have never doped, and, unlike many of my accusers, I have competed as an endurance athlete for 25 years with no spike in performance, passed more than 500 drug tests and never failed one."
The Post cited a 15-page charging letter by the USADA.
It said the agency, which oversees anti-doping in Olympic sports in the United States, was empowered to bring charges that could lead to suspension from competition and the rescinding of awards but did have not authority to bring criminal charges.
A spokesman for the USADA was not immediately available to comment.
Armstrong said: "These are the very same charges and the same witnesses that the Justice Department chose not to pursue after a two-year investigation."
In February, the U.S. Justice Department dropped an investigation centered on whether Armstrong and his teammates cheated the sponsor of their bike racing team with a secret doping program.
That decision meant that Armstrong, a cancer survivor and one of his sport's greatest champions who has always vehemently denied using performance-enhancing drugs, would not face criminal charges from the two-year-long probe.
ARMSTRONG NEVER TESTED POSITIVE
At that time, however, the USADA said the end of the Justice Department's criminal probe did not mean the doping agency would not pursue its own course of action.
"Unlike the U.S. Attorney, USADA's job is to protect clean sport rather than enforce specific criminal laws," USADA Chief Executive Officer Travis Tygart said in a written statement at that time. "Our investigation into doping in the sport of cycling is continuing and we look forward to obtaining the information developed during the federal investigation."
Doping, or using performance enhancing substances in professional sports, is not in itself a federal crime.
The Post said it had obtained a charging letter dated June 12, in which the USADA made previously unpublicized allegations against Armstrong. It alleges it collected blood samples from Armstrong in 2009 and 2010 that were "fully consistent with blood manipulation including EPO use and/or blood transfusions."
EPO is erythropoietin, a naturally occurring protein, and its use is one recent way athletes have tried to artificially boost their red blood cell count and athletic performance.
Armstrong has never tested positive.
The Post said the USADA's letter alleges that Armstrong and five former cycling team associates engaged in a doping conspiracy from 1998-2011.
The letter specifically alleges that Armstrong used EPO, blood transfusions, testosterone, corticosteroids and masking agents and that he distributed and administered drugs to others.
The Texas-born cyclist last Tour de France victory was in 2005 and he has since taken up competing in triathlons.
