WASHINGTON – Seven-time Tour de France champion Lance Armstrong asked a US Anti-Doping Agency review board Friday to dismiss “spurious” allegations brought against him last week. Armstrong's attorney Robert Luskin replied to USADA's claims that the famed US cyclist was part of a doping conspiracy in an 18-page letter obtained by the Washington Post and linked to Armstrong's Twitter account. Luskin said USADA had not submitted proper evidence to support its claims that Armstrong was a dope cheat. “USADA has submitted no evidence to support its spurious allegations,” Luskin wrote. — AP
