The US government today sued former CIA employee and NSA sysadmin contractor Edward Snowden to deny him payment from his newly published book, Permanent Record.

The civil lawsuit [PDF], filed in the Eastern District of Virginia, alleges that Snowden violated non-disclosure agreements signed as a condition of employment with the CIA and NSA. Those agreements require signatories to submit books to the respective agencies for review, prior to publication, to ensure classified information isn't disclosed.
