A confidential memo from one of the most secretive panels in Congress was leaked on a peer-to-peer file-sharing network, publicly detailing sensitive probes involving more than 30 lawmakers and aides.

In July, the same month the confidential memo was prepared, a separate House committee held hearings on whether federal laws were needed to protect federal employees from accidental file sharing. Legislators have grown so worried about inadvertent leaking of documents over P2P networks they've considered draconian bills that could render entire web browsers and operating systems illegal.
