From the NationaL Review "FBI Rewrites Federal Law"

According to Director James Comey, Hillary Clinton checked every box required for a felony violation of Section 793(f) of the federal penal code (Title 18): With lawful access to highly classified information she acted with gross negligence in removing and causing it to be removed it from its proper place of custody, and she transmitted it and caused it to be transmitted to others not authorized to have it, in patent violation of her trust. Director Comey even conceded that former Secretary Clinton was “extremely careless” and strongly suggested that her recklessness very likely led to communications (her own and those she corresponded with) being intercepted by foreign intelligence services.
