President Obama said he has "no evidence at this point from what I've seen that classified information was disclosed" as part of the scandal surrounding former CIA Director David H. Petraeus and Gen. John Allen.

In his first public remarks on the Petraeus scandal, Obama would not fault the FBI for failing to notify the White House earlier that the CIA director had been ensnared in an investigation. Obama said the timing was governed by FBI protocols and that "we want to make sure that we don't prejudge these kinds of situations."

White House Press Secretary Jay Carney said Tuesday that Obama was caught off-guard by the disclosure of Petraeus's problems. Obama didn't learn of the matter until Thursday and accepted Petraeus's resignation on Friday.
