AUSTIN, Texas (AP) -- Lance Armstrong's legal team says Floyd Landis and Tyler Hamilton, former Armstrong teammates who have admitted using performance-enhancing drugs, are part of the U.S. Anti-Doping Agency's efforts to prove the cyclist doped during his record-setting career.
A letter sent from Armstrong's attorneys to USADA on Wednesday says the agency's alleged evidence against Armstrong includes previously disclosed Landis emails and Hamilton's 2011 interview with "60 Minutes." Both men accused Armstrong of doping.
Armstrong says he's innocent. USADA has said at least 10 former Armstrong teammates and associates will testify against him. The agency has said it would keep their names confidential to protect them from intimidation.
The letter was the first mention of specific names behind the allegations that Armstrong cheated while winning the Tour de France from 1999-2005.
