PARIS (AP) — The head of the U.S. Anti-Doping Agency says he has received death threats during his investigation of Lance Armstrong.
In an interview with French sports daily L'Equipe on Monday, USADA chief executive Travis Tygart says "the Armstrong affair has prompted death threats against me" and that he received three threats from separate individuals.
In August, Armstrong dropped any further challenges to USADA's allegations that he took performance-enhancing drugs to win the Tour de France from 1999-2005. A day later, USADA stripped Armstrong of his Tour titles and banned him for life.
The International Cycling Union has yet to ratify USADA's decision to strip Armstrong, saying it needs to see evidence first.
Tygart says USADA will provide the files to the UCI "by the end of the month."
