The Justice Department joined a lawsuit Friday against disgraced cyclist Lance Armstrong that alleges the former seven-time Tour de France champion concealed his use of performance-enhancing drugs and defrauded his longtime sponsor, the U.S. Postal Service.

Lance Armstrong will not do a tell-all interview under oath to help bring down the organized crime network, which helped facilitate his use of performance-enhancing drugs and which many believe is still deeply involved in today's pro cycling.

It's 2013 and time for harsher punishments.

A "monumental cloud" will hang over Spanish sport until all the athletes involved in the Operation Puerto case are identified, according to the head of the World Anti-Doping Agency (WADA).

The International Cycling Union (UCI) did all it could to stall its doping investigation into Lance Armstrong, U.S. Anti-Doping Agency chief executive Travis Tygart said Wednesday.

The World Anti-Doping Agency called the UCI "deceitful" Tuesday for shutting down its independent doping panel and said it won't participate in an amnesty commission set up by the cycling governing body.

The International Cycling Union (UCI) disbanded what is claimed was an independent commission put together to review any involvement the cycling governing body had in the Lance Armstrong scandal, saying it will go ahead with a "truth and reconciliation commission" instead.

The first public hearing into the Lance Armstrong doping scandal descended into sharp exchanges in London on Friday over the lack of disclosure of documents by the sport's governing body.

The World Anti-Doping Agency (WADA) disputes a claim by former international cycling union (UCI) president and current honorary president Hein Verbruggen that discussing suspicious doping samples with athletes was the normal practice in sports.

UCI Honorary President Hein Verbruggen says the International Cycling Union (UCI) held meetings with riders, including Lance Armstrong, to warn them when suspicious test values showed they were coming close to testing positive for performance enhancing drugs.
