Washington D.C. (NNCNOW.com) --- There are new developments in the scandal that led to the resignation of CIA Director David Petraeus.
Monday night, Defense Secretary Leon Panetta announced that General John Allen, our top military commander in Afghanistan, is under investigation.
The Pentagon discovered 20,000 to 30,000 pages of e-mails that a senior defense official called "potentially inappropriate" between Allen and Jill Kelley, the woman who complained she felt harassed by anonymous e-mails later traced to Paula Broadwell.
The FBI's investigation into those anonymous e-mails uncovered an affair between Broadwell and CIA Director David Petraeus. Petraeus resigned last week once the investigation went public.
During that investigation, agents discovered emails between Petraeus and Broadwell that were indicative of an extramarital affair between them, according to government and law enforcement officials.
The Pentagon won't say what the relationship was between Allen and Kelley following this new development. However, Allen is still on the job for now in Washington.
Allen has already been nominated to take over the military in Europe with his confirmation hearing set for Thursday, however that hearing is now on hold pending the results of this investigation.
A senior defense official also said the general “disputes that he has engaged in any wrongdoing in this matter.”
The Pentagon's inspector general is investigating Allen. Senior military sources say these latest allegations took them by surprise.
NBC News has tried to reach those involved in this investigation, however no one has responded to requests for comments yet.
