Jonathan Alter of Newsweek asks "Is Rove a Security Risk?"
Scooter Libby's indictment reveals that Official A discussed Valerie Wilson's covert status with reporters. Official A is now known to be Karl Rove.
So far, Rove has escaped indictment for his role in the Plame leak. However, as Alter explains, security clearances can be revoked for negligent disclosures as well as deliberate leaks:
Under Executive Order 12958, signed by President Clinton in 1995, such a disclosure [as Rove's] is grounds for, at a minimum, losing access to classified information.
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.
It's hard to imagine how the conduct of Official A could be consistent with ongoing security clearance.
Rove certainly wouldn't be the first official to have his security clearance revoked for such an infraction.
The onus is on the White House to explain why Rove is allowed to continue to occupy his privileged position, given the grave suspicions surrounding his conduct in the Plame case.
