WASHINGTON (AP) - Lawmakers are digging into the tangled tale of emails that exposed an extramarital affair ending David Petraeus' CIA career and led investigators to a questionable relationship between a Florida socialite and the general commanding the war in Afghanistan.
Their main question: Was national security threatened?
The extramarital affair was between Petraeus and his biographer Paula Broadwell, who U.S. officials say sent harassing, anonymous emails to a woman she apparently saw as a rival for Petraeus' affections. That woman, Jill Kelley, in turn traded thousands of sometimes flirtatious messages with Gen. John Allen, possible evidence of another inappropriate relationship.
The CIA's acting director, Michael Morell, started answering lawmakers' questions Tuesday on Capitol Hill, meeting with top Senate intelligence officials to explain the CIA's take on events that led to Petraeus' resignation last week after he acknowledged the affair. The lawmakers are especially concerned over reports that Broadwell had classified information on her laptop, though FBI investigators say they concluded there was no security breach.
President Barack Obama is expected to make his first comments on the widening scandal Wednesday, during a postelection news conference at the White House.
Obama had hoped to use the afternoon news conference, his first since his re-election, to build support for his economic proposals heading into negotiations with lawmakers on the so-called fiscal cliff. But the scandal could overshadow his economic agenda this week, derail plans for a smooth transition in his national security team and complicate war planning during a critical time in the Afghanistan war effort.
Allen has been allowed to stay in his job as commander of the Afghan war and provide a leading voice in White House discussions on how many troops will remain in Afghanistan - and for what purposes - after the U.S.-led combat operation ends in 2014. But Obama put on hold Allen's nomination to become the next commander of U.S. European Command as well as the NATO supreme allied commander in Europe, at the request of Defense Secretary Leon Panetta, until Pentagon investigators are able to sift through the 20,000-plus pages of documents and emails that involve Allen and Kelley.
The FBI decided to turn over the Allen information to the military once the bureau recognized it contained no evidence of a federal crime, according to a federal law enforcement official who was not authorized to discuss the matter on the record and demanded anonymity. Adultery, however, is a crime under the Uniform Code of Military Justice.
Allen, 58, insisted he'd done nothing wrong and worked to save his imperiled career.
At a news conference Wednesday in Perth, Australia, Panetta said no one should "leap to any conclusions," and said he is fully confident in Allen's ability to continue to lead in Afghanistan. He added that putting a hold on Allen's European Command nomination was the "prudent" thing to do.
Known as a close friend of Petraeus, Kelley, 37, triggered the FBI investigation that led to the retired four-star general's downfall as CIA director when she complained about getting anonymous, harassing emails. They turned out to have been written by Petraeus' mistress, Broadwell, who apparently was jealous of the attention the general paid to Kelley.
In the course of looking into that matter, federal investigators came across what a Pentagon official called "inappropriate communications" between Allen and Kelley, both of them married.
A senior U.S. official told The Associated Press that other senior U.S. officials who read the emails determined that the exchanges between Allen and Kelley were not sexually explicit or seductive but included pet names such as "sweetheart" or "dear." The official said that while much of the communication - including some from Allen to Kelley - is relatively innocuous, some could be construed as unprofessional and would cause a reasonable person to take notice.
That official and others who described the investigation requested anonymity on grounds that they were not authorized to discuss the situation publicly.
Kelley served as a sort of social ambassador for U.S. Central Command in Tampa, Fla., hosting parties for Petraeus when he was commander there from 2008-10. The friendship with the Petraeus began when they arrived in Tampa, and the Kelleys threw a welcome party at their home, a short distance from Central Command headquarters, introducing the new chief and his wife, Holly, to Tampa's elite, according to staffers who served with Petraeus.
Such friendships among senior military commanders and prominent local community leaders are common at any base.
On Capitol Hill, lawmakers complained that they should have been told about the investigation earlier. Morell, who took over Petraeus' duties at the CIA, met with Senate Intelligence Committee Chairwoman Dianne Feinstein, D-Calif., and ranking Republican Saxby Chambliss of Georgia
on Tuesday. He was expected to meet with the leaders of the House intelligence committee on Wednesday.
Asked by reporters if there was a national security breach with the Petraeus affair, Feinstein said, "I have no evidence that there was at this time." She said she expected Petraeus to testify this week or next.
The Senate Armed Services Committee planned to go ahead with Thursday's scheduled confirmation hearing on the nomination of Marine Corps Gen. Joseph Dunford, who is to replace Allen as commander of U.S. and NATO forces in Afghanistan, if Allen is indeed promoted.
Sen. Carl Levin, chairman of the Armed Services Committee, said Petraeus should still testify about the September attack on the U.S. Consulate in Benghazi, Libya, "if he has relevant information."
