WASHINGTON (AP) - David Petraeus, the retired four-star general renowned for taking charge of the military campaigns in Iraq and then Afghanistan, abruptly resigned Friday as director of the CIA, admitting to an extramarital affair.
The affair was discovered during an FBI investigation, according to officials briefed on the developments. They spoke on condition of anonymity because they were not authorized to publicly discuss the matter. It was unclear what the FBI was investigating or when it became aware of the affair.
Petraeus' resignation shocked Washington's intelligence and political communities. It was a sudden end to the public career of the best-known general of the post 9/11 wars, a man sometimes mentioned as a potential Republican presidential candidate. His service was effusively praised Friday in statements from lawmakers of both parties.
CIA Director David Petraeus, shown testifying on Capitol Hill in Washington, has resigned because of an extramarital affair.
Petraeus, who turned 60 on Wednesday, told CIA employees in a statement that he had met with President Barack Obama at the White House on Thursday and asked to be allowed to resign. On Friday, the president accepted.
Petraeus told his staffers he was guilty of "extremely poor judgment" in the affair. "Such behavior is unacceptable, both as a husband and as the leader of an organization such as ours."
He has been married for 38 years to Holly Petraeus, whom he met when he was a cadet at the U.S. Military Academy at West Point, N.Y. She was the daughter of the academy superintendent. They have two children, and their son led an infantry platoon in Afghanistan.
Obama said in a statement that the retired general had provided "extraordinary service to the United States for decades" and had given a lifetime of service that "made our country safer and stronger." Obama called him "one of the outstanding general officers of his generation."
The president said that CIA Deputy Director Michael Morell would serve as acting director. Morell was the key CIA aide in the White House to President George W. Bush during the Sept. 11, 2001, terror attacks.
"I am completely confident that the CIA will continue to thrive and carry out its essential mission," Obama said.
The resignation comes at a sensitive time. The administration and the CIA have struggled to defend security and intelligence lapses before the attack that killed the U.S. ambassador to Libya and three others. It was an issue during the presidential campaign that ended with Obama's re-election Tuesday.
The CIA has come under intense scrutiny for providing the White House and other administration officials with talking points that led them to say the Benghazi attack was a result of a film protest, not a militant terror attack. It has become clear that the CIA was aware the attack was distinct from the film protests roiling across other parts of the Muslim world.
For the director of the CIA, being engaged in an extramarital affair is considered a serious breach of security and a counterintelligence threat. If a foreign government had learned of the affair, the reasoning goes, Petraeus or the person with whom he was involved could have been blackmailed or otherwise compromised. Military justice considers conduct such as an extramarital affair to be possible grounds for court martial.
Petraeus became CIA director in September 2011.
