Congress: FBI should have told us about Petraeus

(CBS News) As Congress broadens its investigations into David Petraeus and his affair, key members of House and Senate committees say the FBI should not have left them out of the loop.

Petraeus tryst just salacious - or dangerous?

Sen. Olympia Snowe, R-Maine, is on the Intelligence Committee and says the Petraeus affair and FBI probe which intercepted personal emails, adds another dimension. "Should the president have known sooner?" she said. "What was the basis for this investigation, what steps were taken by the FBI to initiate this investigation in the first place? Was a court-order secured?"

Chairman of the House Homeland Security Committee Peter King, R-N.Y., has his own questions for the FBI. "Not telling the intelligence community about that is wrong, absolutely wrong," King said. "The FBI's going to have to explain itself to the committee, if not, there's going to be consequences."

For the first time, Defense Secretary Leon Panetta commented to reporters about Petraeus, calling it a "very sad situation" for the general's career to end in scandal. Reporters asked whether the former general could be prosecuted if the affair began while he was on active duty.

"You know, I don't know, I don't know the answer to that," Panetta answered. "I'm reading the papers like you are to determine just what the committee finds out, what the ultimate investigation determines on that issue."

Republican Sen. Lindsey Graham, S.C., is pushing for a joint bipartisan House-Senate committee to investigate the scandal, saying it's grown too vast and intertwined for individual committees to investigate separately.
