CHAMBERY, France (AP) - Lance Armstrong says he will cooperate with a "fair investigation" but not a "witch hunt" into allegations that he and his former cycling team were involved in doping.
Armstrong is responding to reports of a federal investigation of possible fraud and doping charges against him and former associates.
His remarks came at the Tour de France, where he is 31st overall.
The New York Times reported that authorities have issued grand jury subpoenas to witnesses as part of the probe into allegations made by American cyclist Floyd Landis.
Landis, who was stripped of his 2006 Tour title for doping, has said the use of banned substances was common on the US Postal team when he rode with Armstrong.
