WASHINGTON (AP) - Top national security officials trudged to Capitol Hill on Thursday to grapple with fallout from the David Petraeus sex scandal as Defense Secretary Leon Panetta asked service chiefs to review ethics training for military officers. He said he was unaware of any other top brass who could turn out to be ensnared in the debacle.
One person missing from the tableau: Afghan war chief Gen. John Allen, whose nomination to take over in Europe is on hold because of suggestive emails turned up in the investigation.
Legislators went forward with a hearing on the nomination of Gen. Joseph Dunford to replace Allen in Afghanistan. But with Allen's own future uncertain, they put off consideration of his promotion to U.S. European Command chief and NATO supreme allied commander. Allen had initially been scheduled to testify.
Panetta, speaking at a news conference in Bangkok, gave new words of support to Allen, voicing "tremendous confidence" in the general.
Citing a string of ethical lapses by senior military officers, however, Panetta asked the Joint Chiefs of Staff to review ethics training and look for ways to help officers stay out of trouble.
Sen. John McCain, R-Ariz., opened Dunford's hearing with kind words for Allen, saying, "I continue to believe that General Allen is one of our best military leaders. And I continue to have confidence in his ability to lead the war in Afghanistan."
Leading administration officials, meanwhile, met privately with lawmakers for a third straight day to explain how the Petraeus investigation was handled and explore its national security implications. Among those appearing before the House Intelligence Committee: Director of National Intelligence James Clapper and Acting CIA Director Michael Morell.
Petraeus, the much-honored retired general, resigned his CIA post Friday after acknowledging an extramarital affair with his biographer, Paula Broadwell. The FBI began investigating the matter last summer but didn't notify the White House of Congress until after the election.
The CIA on Thursday opened an "exploratory" investigation into Petraeus' conduct. The inquiry "doesn't presuppose any particular outcome," said CIA spokesman Preston Golson. At the same time, Army officials say that, at this point, there is no appetite for recalling Petraeus to active duty to pursue any adultery charges against him.
In the course of investigating the Petraeus situation, the FBI uncovered suggestive emails between Allen and Florida socialite Jill Kelley, both of them married. President Barack Obama then put Allen's promotion nomination on hold.
Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, said he expects Allen to eventually take over the European Command, but he acknowledged, "I see this investigation and how long it could take affecting that."
Dempsey said he "absolutely" had confidence in Allen's ability to continue in command in Afghanistan despite the distraction of the scandal. He spoke in an interview with American Forces Press Service.
While Allen's nomination has been put on hold, the fact that it wasn't immediately withdrawn suggests there is at least some feeling he could survive the investigation.
The initial expectation is that the Defense Department inspector general's probe into the emails will be done within weeks rather than months. The final decision would likely be made by Panetta and the White House after discussions with Capitol Hill leaders.
