AUSTIN, Texas Lance Armstrong filed a scathing response Friday to the latest doping allegations against him, accusing the U.S. Anti-Doping Agency of violating its own rules and possibly breaking federal law during its investigation.
The agency said Armstrong used performance-enhancing drugs and other improper methods to win cyclings premiere event, the Tour de France, from 1999-2005. Friday was the deadline for Armstrong to respond to USADAs warning that charges were pending before his case moves to the next stage.
Armstrong, who denies doping and notes he has never failed a drug test, could be stripped of his titles and banned from cycling, though he retired from the sport last year.
In their 11-page document, Armstrongs attorneys complained they still havent been allowed to see the evidence against him, including witness names and any expert analysis to support USADAs claim that 2009 and 2010 blood tests are fully consistent with blood doping.
The letter said USADAs case is long on stale allegations disproved long ago and short on evidence and offensive to any notions of due process.
Armstrongs case now goes to a three-person USADA review board, which will decide if there is enough evidence to support the charges. If USADA files formal charges, the case could go to a three-person arbitration panel by November.
The Review Board must recommend that this case not move forward, the letter said.
Armstrongs attorneys made similar claims in previous letters, but Fridays document appeared to lay out his potential legal strategy should he file a federal lawsuit against USADA.
Armstrongs letter argues that USADAs rules allow the review board to consider materials submitted from an accused athlete but complains that he cant mount a legitimate defense until hes able to see the evidence against him. USADA said it is withholding witness identities to protect them from intimidation.
Travis Tygart, USADAs chief executive officer, said in a statement that the rules provide full due process and are designed to get to the truth.
USADAs warning letter to Armstrong said 10 former teammates are willing to testify that they either know he used performance-enhancing drugs or talked about using them and encouraged them within the team. USADA says Armstrong used the blood-booster EPO, steroids and improper blood transfusions.
Armstrongs attorneys say they believe USADA investigators coerced false testimony from witnesses by promising not to charge them with doping; they argue this could violate bribery laws.
They also question whether USADA improperly gained access to testimony in a recent federal grand jury criminal investigation that ended in February with no charges filed against Armstrong.
The letter notes that Tygart participated in witness interviews with federal criminal investigators.
Armstrongs letter also challenged the 2009-2010 blood tests, which were taken during his two-year comeback from retirement. Armstrong passed all his drug tests during that period and posted his testing results on his website, Livestrong.com, and no charges were brought, the letter said.
It also said most of the allegations fall outside of USADAs eight-year statute of limitations, but the agency argues that Armstrong keeps expanding the time limit by continuing to deny drug use.
USADA has said it is also pursuing doping charges against Johan Bruyneel, the manager of Armstrongs winning Tour de France teams; team doctors Pedro Celaya and Luis Garcia del Moral; team trainer Pepe Marti, and consulting doctor Michele Ferrari.
Bruyneel, who now leads the RadioShack-Nissan-Trek team, said Friday he wont attend this years Tour de France because the allegations would be a distraction for his team and the race. Bruyneel says he is innocent.
