Armstrong: Hamilton 'a confessed liar'

Seven-time Tour de France winner Lance Armstrong has made furious attacks on former team-mates, the broadcaster CBS and a federal investigator after the latest drug claims against him.

The Texan launched a website www.facts4lance.com after CBS began trailing excerpts from a documentary about Armstrong which included claims from Olympic gold medallist Tyler Hamilton that he had seen his one-time US Postal team-mate inject EPO.
