U.S. sues disgraced cyclist Armstrong for sponsor money

WASHINGTON (Reuters) - The United States accused cyclist Lance Armstrong on Friday of defrauding the U.S. Postal Service by taking its sponsorship money at the same time he was doping and using performance-enhancing drugs in violation of cycling rules.

The government joined a civil suit against Armstrong, stripped of his seven Tour de France titles and banned for life from cycling in 2012 after accusations he had cheated for years. In January, he said the accusations were true in an interview with television host Oprah Winfrey.
