Lance Armstrong filed a federal lawsuit Monday aimed at preventing the U.S. Anti-Doping Agency from moving ahead with charges that he used performance-enhancing drugs during his record-setting career. Armstrong’s lawsuit says USADA rules violate athletes’ constitutional right to a fair trial, and that the agency doesn’t have jurisdiction in his case. It also accuses USADA’s chief executive, Travis Tygart, of waging a personal vendetta against the cancer survivor who won the Tour de France every year from 1999 to 2005.
