WASHINGTON (AP) -- A U.S. official says the Army has suspended the security clearance of the woman who had an affair with CIA Director David Petraeus, triggering his resignation.

Paula Broadwell, a West Point graduate, is a former Army intelligence officer and held a high security clearance. Because her clearance was issued through the Army, it was the service's move to suspend it.

It's not unusual for someone's clearance to be suspended if that person is under investigation, particularly in cases of possible security breaches. Officials say that an FBI investigation has revealed that Broadwell sent emails to another woman warning her to stay away from Petraeus. The FBI also found possibly classified documents on Broadwell's computer.

The official was not authorized to speak publicly about the clearance so requested anonymity.
