CHARLOTTE, NC (WBTV/AP/CBS News) - Former CIA Director David Petraeus will testify before Congress early Friday morning, behind closed doors.
Government officials say he will speak to two panels regarding the deadly consulate attack in Libya on September 11th that killed U.S. Ambassador Chris Stevens. It is not clear if he will be questioned about his resignation as CIA director.
Meanwhile, Attorney General Eric Holder revealed Thursday that Charlotte author Paula Broadwell was interviewed by federal investigators on November 2nd, exactly one week before David Petraeus resigned. Holder said Broadwell, Petraeus' alleged mistress, had "substantial" amounts of classified information in her Dilworth home.
This past Wednesday, two-high-ranking members of the House Intelligence Committee held a hearing on the timeline of events that led to Petraeus' resignation.
About a dozen FBI agents spent several hours inside Broadwell's Dilworth home Monday night in search of what sources told CNN, at the time, was possible classified information.
The agents were seen carrying boxes and taking photographs inside the home. A WBTV photographer says at least two computers were taken from the home as well.
Thursday afternoon, two people - a man and a woman - were seen entering the Broadwell home. They left with a couple bags, one of which had clothes, a short time later. There is no word who the pair is, or how they are connected to the Broadwell family. News crews noted the pair did have a key to the home.
Broadwell, who is married with two young sons, has not been seen in Charlotte since word of the alleged affair was made public last Friday. She was only spotted in Washington, D.C. at her brother's home. Broadwell has responded to multiple emails and phone messages. Broadwell planned to celebrate her 40th birthday party in Washington last weekend, with many reporters invited.
This was during the period while he led the International Security Assistance Force there.
Last Friday, it was announced that Petraeus gave his resignation to President Barack Obama, citing the affair.
An investigation started with harassing emails sent by Broadwell to another woman and eventually led the FBI to discover the affair, U.S. officials told The Associated Press on Saturday.
The official said the FBI investigation began several months ago with a complaint against Broadwell, a 40-year-old graduate of the U.S. Military Academy and an Army Reserve officer.
A Florida woman who allegedly received harassing emails from Broadwell which led federal investigators to discover Petraeus' sexual indiscretion with Broadwell.
A senior U.S. military official identified the second woman as Jill Kelley, 37, who lives in Tampa, Fla., and serves as an unpaid social liaison to MacDill Air Force Base in Tampa, where the military's Central Command and Special Operations Command are located.
Staffers for Petraeus said Kelley and her husband were regular guests at events he held at Central Command headquarters.
In the alleged harassing emails, The Wall Street Journal reports Broadwell says she witnessed Kelley touching Petraeus provocatively under a table. In another email, the Journal reports Broadwell asked if Kelley's husband was aware of the actions. In a third email, Broadwell is accused of saying to Kelley, quote "who do you think you are?"
Kelley allegedly reported the emails to the FBI - and their investigation is what uncovered Broadwell's affair with Petraeus.
In a statement Sunday, Kelley and her husband, Scott, said: "We and our family have been friends with Gen. Petraeus and his family for over five years. We respect his and his family's privacy and want the same for us and our three children."
According to a friend and former top aide, the affair began in 2011, two months after Petraeus took the reins as CIA director. It reportedly ended nearly 4 months ago.
Petraeus and his family are said to be devastated over the affair, especially his wife Holly, who "is not exactly pleased right now," said Steve Boylan, a friend and former Petraeus spokesman who spoke to Petraeus over the weekend.
"After being married for over 37 years, I showed extremely poor judgment by engaging in an extramarital affair," Petraeus said in the letter to the CIA workforce on Friday. "Such behavior is unacceptable, both as a husband and as the leader of an organization such as ours."
Concerned the emails he exchanged with Broadwell raised the possibility of a security breach, the FBI brought the matter up with Petraeus directly, according to the official, who spoke on condition of anonymity because he was not authorized to publicly discuss the investigation.
The FBI approached the CIA director, who earned acclaim for his leadership of the wars in Iraq and Afghanistan, because his emails in the matter were in most instances sent from a personal account, not his CIA one.
By Friday evening, multiple officials identified Broadwell, who spent the better part of a year reporting on Petraeus' time in Afghanistan.
CIA officers long had expressed concern about Broadwell's unprecedented access to the director.
She frequently visited the spy agency's headquarters in Langley, Va., to meet Petraeus in his office, accompanied him on his punishing morning runs around the CIA grounds and often attended public functions as his guest, according to two former intelligence officials.
As a military intelligence officer in the Army Reserve, Broadwell had a high security clearance, which she mentioned at public events as one of the reasons she was well-suited to write Petraeus' story.
But her access was unsettling to members of the secretive and compartmentalized intelligence agency, where husbands and wives often work in different divisions, but share nothing with each other when they come home because they don't "need to know."
In one incident that caught the CIA staff by surprise, Broadwell posted a photograph on her Facebook page of Petraeus with actress Angelina Jolie, taken in his 7th floor office where only the official CIA photographer is permitted to take photos.
Petraeus had apparently given Broadwell the photo just hours after it was taken.
Petraeus' staff in Afghanistan similarly had been concerned about the time Broadwell spent with their boss on her multiple reporting visits to the war zone.
Following standard military procedure with senior officers, they almost always had another staffer present when she met with him at his headquarters, though they did have some meetings alone.
Military officers close to him insist the affair did not begin when he was in uniform.
