Lance Armstrong, the seven-time Tour de France champion, has asked a U.S. judge to launch a probe into alleged leaks of grand jury proceedings examining cycling, that were supposed to remain sealed.

Each leak has revealed information damaging to Armstrong's reputation and has been carefully calculated to drum up publicity and cultivate public support for an investigation that is, to say the least, questionable in both its motive and its merits, Armstrong's legal team wrote in its motion.

The motion also requested that prosecutors also show why they shouldn't be held in contempt of court.

Armstrong is currently involved in a federal doping investigation. In addition, he has come under intense public scrutiny for the usage of performance enhancing drugs (PEDs) after accusations from former teammates.

After former teammate Floyd Landis confessed to the usage of PEDs, he also accused Armstrong of doing the same.

Former teammate and Olympic champion Tyler Hamilton went on 60 Minutes to say that he also used PEDs and accused Armstrong not only of using PEDs, but also encouraging his team to use them and covering it up.
