The U.S. Justice Department has joined Floyd Landis's whistle-blower lawsuit against disgraced cyclist Lance Armstrong.
According to Armstrong's lawyers, the "lawsuit alleges the former Tour de France champion concealed his use of performance-enhancing drugs for over a decade and defrauded his long-time sponsor, the U.S. Postal Service."
Armstrong tried to reach a plea deal with the federal government, but his lawyer, Robert Luskin, told the Associated Press on Friday that the two parties failed because they disagreed "about whether the postal service was damaged."
Because the Justice Department has joined the lawsuit, it will be unsealed.
Armstrong, after denying for years that he had doped, admitted last month to Oprah Winfrey that he had used performance-enhancing drugs to win all of his Tour de France titles.
