WASHINGTON, Aug 7 - Embattled Tour de France winner Floyd Landis vowed on Monday to clear his name.

"I have a new goal, to prove myself innocent," Landis told ABC's Good Morning America.

Samples taken from Landis during last month's Tour revealed excessive amounts of the male sex hormone testosterone and the American faces being stripped of victory and a two-year ban.

The U.S. Cycling Federation has already referred the case to the United States Anti-Doping Agency (USADA).
