Key witnesses in Armstrong doping case
A look at the former teammates of Lance Armstrong who were listed as key witnesses in the U.S. Anti-Doping Agency's case against the famed cyclist:
George Hincapie: Only cyclist with Armstrong for all seven of his Tour de France victories (1999-2005) and one of Armstrong's most trusted lieutenants. His testimony detailing participating in a doping program and Armstrong's drug use is considered crucial to USADA's case because of their friendship, although the two reportedly have not spoken in several months.
Tyler Hamilton: Rode with Armstrong from 1998-2001. Detailed complex team doping program of drug use and blood transfusions in testimony and his recent book "The Secret Race." Said Armstrong gave him EPO and took blood transfusions. Twice banned for doping and stripped of his 2004 Olympic gold medal.
Floyd Landis: U.S. Postal Service team rider from 2002-2004. Was first rider to give investigators explicit detail of complex team doping program. Won 2006 Tour de France with a different team but was later stripped of that victory for steroid use. His testimony helped launch federal criminal probe of Armstrong and Postal team that was closed in February with no charges filed.
Frankie Andreu: Armstrong teammate from 1992-2000, one-time roommate and friend for several years. Co-captain of the 2000 Postal team. Andreu and his wife, Betsy, said Armstrong told doctors treating his cancer in 1996 that he used performance-enhancing drugs.
Michael Barry: Armstrong teammate from 2002-2005. Said he participated in doping program.
Tom Danielson: Armstrong teammate in 2005. Spoke about his experience as a young rider on the team.
Levi Leipheimer: Well-respected American rider who was Armstrong teammate for five years on Postal (2000-2001), Astana (2009) and RadioShack (2010-11). Described knowledge of doping program.
Christian Vande Velde: Postal team rider 1998-2003. Testified Armstrong was enforcer of team doping program.
Jonathan Vaughters: Armstrong teammate from 1998-1999 and current director of Garmin-Slipstream team, who testified about EPO use and Postal's system to avoid drug testers.
David Zabriskie: Postal rider from 2001-2004. Testified about doping climate on the team.
Stephen Swart: Rode with Armstrong on Motorola team in 1995. Said Armstrong wanted team to begin doping program.
