AUSTIN, Texas (AP) -- In a letter to federal authorities, a Wisconsin congressman equates the anti-doping charges against Lance Armstrong to a conspiracy theory and calls the U.S. Anti-Doping Agency's authority over the seven-time Tour de France winner "strained at best."
Rep. James Sensenbrenner, a Republican, wrote the Office of National Drug Control Policy on Thursday questioning the nearly $10 million in public funding USADA receives and its procedures investigating and charging athletes with doping violations.
USADA charged Armstrong last month with using performance-enhancing drugs while winning the Tour de France from 1999-2005. He maintains his innocence and sued in federal court to block the case from moving forward.
USADA chief executive Travis Tygart says the evidence against Armstrong is overwhelming and the agency is willing to discuss its policies and funding with Sensenbrenner.
