Landis vows to clear his name

Embattled Tour de France winner Floyd Landis has vowed 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 US Cycling Federation has already referred the case to the United States Anti-Doping Agency (USADA).
