U.S. sues Lance Armstrong

Lance Armstrong was stripped of his seven Tour de France titles and banned for life after the International Cycling Union (UCI) ratified the United States Anti-Doping Agency's (USADA) sanctions against him. The Justice Department formally filed its case against

Lance Armstrong and his company Tailwind Sports for millions of dollars

that the U.S. Postal Service spent to sponsor the cycling team.
