WASHINGTON - Disgraced cyclist Lance Armstrong has failed to talk the U.S. government out of suing him to recover sponsorship money that the U.S. Postal Service paid his teams to compete in international events, Armstrong's lawyer said on Friday.
Lawyer Robert Luskin said: "Lance and his representatives worked constructively over these last weeks with federal lawyers to resolve this case fairly, but those talks failed because we disagree about whether the Postal Service was damaged."
"The Postal Service's own studies show that the service benefited tremendously from its sponsorship - benefits totaling more than $100 million," the lawyer said in a statement.
A U.S. Justice Department spokeswoman had no immediate comment.
Former Armstrong teammate Floyd Landis was believed to have filed a sealed whistleblower suit against Armstrong in 2010. A decision by the government to join the suit would trigger its unsealing.
Public court records did not indicate that a lawsuit had been filed as of mid-day on Friday.
