FILE - In this July 10, 2010, file photo, Lance Armstrong throws out his water bottle in the last kilometers of the climb toward Station les Rousses, France, during the seventh stage of the Tour de France cycling race. The New York Times reported Friday, Jan. 4, 2013, that Armstrong, who has strongly denied the doping charges that led to him being stripped of his seven Tour de France titles, has told associates he is considering admitting to the use of performance-enhancing drugs. Armstrong attorney Tim Herman denied that Armstrong has reached out to USADA chief executive Travis Tygart and David Howman, director general of the World Anti-Doping Agency.
