Gen. John Allen, commander of the International Security Assistance Force in Afghanistan, is under investigation for alleged "inappropriate communications" with Jill Kelley, the woman who is said to have received threatening emails from Paula Broadwell, the woman with whom former
CIA Director David Petraeus had an extramarital affair.
The FBI has uncovered "potentially inappropriate" emails between Allen and Kelly, according to a senior U.S. defense official who is traveling with Defense Secretary Leon Panetta. The department is reviewing between 20,000 and 30,000 documents connected to this matter, the official said. The email exchanges between Kelley and Allen took place from 2010 to 2012.
