According to a congressional aide familiar with the matter, the House and Senate intelligence committees weren't informed that there was an FBI investigation before November 9.
Obama is also made aware of the investigation into Allen when the Department of Justice notifies White House counsel that there may be an issue associated with Allen's nomination, according to National Security Council spokesman Tommy Vietor.
Lawmakers complain in televised interviews that the FBI didn't alert them sooner to the investigation.
Sen. Dianne Feinstein, D-California, who chairs the Senate intelligence committee, says on Fox: "We received no advance notice; it was like a lightning bolt."
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.
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.
