Armstrong's confession could lead to $100 million whistleblower lawsuit

The United States Justice Department is considering joining a federal whistleblower lawsuit reportedly filed by Floyd Landis, according to the Wall Street Journal. The suit is aimed at recouping the sponsorship funds provided by the US Postal Service, which supported the team from 1996-2004, in light of the US Anti-Doping Agency's lifetime ban of Lance Armstrong for doping.
