The Army has revoked the promotion of Paula Broadwell, the one-time mistress of CIA Director David Petraeus, according to a Defense Department official.

Broadwell, a major in the Army reserves, had been approved last August for promotion to lieutenant colonel. The Army made the decision to revoke the promotion earlier this month, a Defense Department official told CNN. The source declined to be named because of the sensitive nature of the personnel information.

Since the Petraeus scandal broke, Broadwell has been under investigation by the Army for having classified information in her home without permission. She was initially on the list of approved promotions back on August 28, 2012. But under Army regulations "if new information comes to light" within six months of a promotion date it could make the person ineligible. Broadwell was deemed ineligible for promotion because she is under investigation for a matter that could result in her being punished by the Army, the official said. The promotion is revoked until the matter is resolved, the official said. If cleared, she would be eligible again.

Her security clearance, which was suspended last year, also has not been reinstated.
