It's NICE to know that we once had a President who thought it was unacceptable to leak classified information. Unlike now, when we have one who thinks such behavior should be winked at.
Section 5.1 of Clinton’s executive order prohibits “any knowing, willful or negligent action that could reasonably be expected to result in an unauthorized disclosure of classified information.” While the law against revealing the identity of a CIA operative requires that the perpetrator intentionally disclosed such classified information (a high standard, which may be one reason Fitzgerald did not indict on those grounds), the executive order covers “negligence,” or unintentional disclosure.
That means the only proper answer to a reporter’s questions about Joseph Wilson’s wife would have been something along the lines of, “You know I cannot discuss who may or may not be in the CIA.” The indictment makes clear that this was not the answer Official A provided when the subject was discussed with reporters Bob Novak and Matt Cooper.
The sanctions for such disclosure are contained in Section 5.7 of the executive order. That section says that “the agency head, senior agency official or other supervisory official shall, at a minimum, promptly remove the classification authority of any individual who demonstrates reckless disregard or a pattern of error in applying the classification standards of this order.” Any reasonable reading of the events covered in the indictment would consider Rove’s behavior “reckless.” The fact that he discussed Plame’s identity with reporters more than once constitutes a pattern.
In the past, other officials have lost their security clearances for similar disclosures—even without a pattern. Former CIA director John Deutch and former national-security adviser Sandy Berger (who got in trouble after leaving office) both lost their clearances when they took classified information home without proper authorization. More recently, officials of the Coast Guard were sanctioned when they warned relatives of a possible terrorist threat against the New York City subways before public disclosure of the threat.
