The FBI has found a substantial amount of classified information improperly saved on the personal computer of disgraced CIA Director General David Petraeus' mistress.
The files were discovered on a machine removed from Paula Broadwell's Charlotte, North Carolina, home as they investigated her affair with Petraeus, whose biography she co-wrote.
Investigators also found documents which Broadwell admitted taking from secure government buildings, adding that the government demanded that they all be returned.
According to the New York Times, the network said the FBI and military were going through the material and prosecutors were deciding whether to charge her with a crime.
"That's why they were pulling so much stuff out of [Broadwell's] place," a source said, referring to a search carried out Monday night, three days after Petraeus quit from his post because of the illegitimate affair.
The discoveries prompted the FBI to step up its probe of Broadwell, who anonymously sent harassing e-mails to Jill Kelley, a married "friend" of Petraeus.
According to the report, Broadwell's top-secret stash was revealed shortly after President Barack Obama told a press conference that "I've seen no evidence at this point from what I've seen that classified information was disclosed in any way that would have had a negative impact on our national security."
Broadwell, a former intelligence officer, also had her high security clearance suspended by the Army, an official said.
Meanwhile, Petraeus is expected to testify at a closed congressional hearing about the Sept. 11 killing of US Ambassador Chris Stevens in Benghazi, Libya, the report added. (ANI)
