Lance Armstrong dismissed claims by Floyd Landis that Armstrong had been involved in doping during his cycling career. "I have nothing to hide," Armstrong said at a hastily called news conference outside of his bus prior to the fifth stage of the Tour of California, which Armstrong was competing in before a crash forced him to withdraw on Thursday. Armstrong added: "I think history speaks for itself here." With his longtime coach Johan Bruyneel standing next to him, Armstrong said Landis seemingly pointed the finger at everyone still involved in the sport. "We have nothing to hide," Armstrong said. "We have nothing to run from." http://sports.espn.go.com/oly/cycling/news/story?id=5204726
