Kelley's identity is revealed by the Associated Press, and she issues a statement asking for privacy.

Kelley's statement: "We and our family have been friends with General 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."

That evening, the FBI notifies the Pentagon of its investigation into Allen's communications with Kelley, a senior official tells CNN.

November 12

Former Petraeus spokesman in Iraq Steve Boyland says Petraeus has told him meetings with Broadwell were "infrequent." He confirms Petraeus had a non-work e-mail account.

He also says Petraeus indicated "there was a possible obsession and she felt she was warding off the competition."

Boyland tells the Daily Mail that after the affair, "David and Paula were still in contact about Paula's dissertation."

Vietor says Fox is "flat out wrong" to suggest Brennan knew about the issue before November 7.

Broadwell retains D.C. criminal defense attorney Robert F. Muse.

At 9 p.m., Broadwell's home in Charlotte is searched to see what classified materials she might have. According to the Charlotte Observer, eight to 10 agents remove several cardboard boxes and bags.

"I don't think this is going to lead to any charges against her," a U.S. official tells CNN. He says an earlier search of Broadwell's computer revealed she had some classified material. Both she and Petraeus had said it did not come from Petraeus.

On Humphries, the FBI agent approached by Kelley, the same official says: "He was never on the case. He passed the information on to others who deal with cyber cases but he never worked the case and didn't receive information on the investigation as it proceeded."

Humphries sent shirtless photos to Kelley before this case ever began, according to an official.

On the same day, a senior U.S. defense official says the FBI uncovered between 20,000 and 30,000 pages of "potentially inappropriate" e-mails between Allen and Kelley. This is later clarified by a senior U.S. official -- many of the e-mails were group aliases rather than directly between Allen and Kelley.

John Nagl, who worked for Petraeus for years, says Petraeus insists he never shared classified information with Broadwell. Her access to Petraeus was "highly unusual but not illegal."

Sen. Susan Collins, R-Maine, says it is "absolutely imperative that General Petraeus come and testify" on Benghazi. "He has a great deal of information that we need." Feinstein agrees.

A U.S. official briefed on some of the details of the Allen e-mails suggests there is no criminal issue. While the documents warrant "further looking at....if there was a clear violation of the UCMJ we'd be handling it differently.'

A source close to Allen tells CNN's Nick Paton Walsh: "There is no affair. She (Kelley) is a bored, rich socialite involved with every single senior commander at CENTCOM, because she worked as an honorary consul."

"He gets an anonymous e-mail from Broadwell about Jill. He e-mails Jill to say that someone is threatening you," adds the official.

CENTCOM says Kelley "has no official position with U.S. Central Command. She is a volunteer and a private citizen, not an employee."

Kelley's access to visit MacDill AFB without an escort is suspended due to the investigation, a Defense Department official says. Kelley had been given special access to the base because of her position as a booster and promoter of programs to help U.S. troops, according to the official.

At a White House news conference, President Obama says he is unaware of any disclosure of classified information that could damage national security in the scandal that caused Petraeus' resignation.

FBI Director Robert Mueller makes unexpected appearance on Capitol Hill and meets lawmakers looking for answers on his agency's handling of the Petraeus investigation. He and his deputy meet Mike Rogers and Dutch Ruppersberger, as well as Sens. Feinstein and Chambliss. Chambliss later tells CNN he disagreed with the FBI explanation of how it handled protocols over the case.

CNN's Fran Townsend is told that any prosecution of Broadwell is unlikely: "It appears the information in question was not substantial -- it may have been a technical violation but was not egregious."

Paula Broadwell's security clearance is suspended.

The FBI agent approached by Kelly about the e-mails is identified as Frederick Humphries, 47, who had been friendly with the Kelleys for years. Lawrence Berger, counsel to Federal Law Enforcement Officers Association, says Humphries reported the information he received to the proper channels and had no further part in case.

A source close to Kelley says she has never "had any inappropriately sexual, romantic, physical relationship with either General Petraeus or General Allen."

November 15

Arrangements are made for Petraeus to testify on the Benghazi attack before House and Senate committees Friday.

Sourcing is CNN or public record if not noted otherwise. The FBI and Justice Department have not gone on the record. Much of the information for May 2012 and later comes from a variety of federal officials largely speaking on background; some comes from friends of Petraeus.
