UNDATED (CBS) -- Members of Congress want to know why the FBI waited until Friday to tell them about the affair that cost CIA Director David Petraeus his job.
Members of Congress say the FBI should have alerted them agents were investigating CIA Director David Petraeus before scandal broke on Friday.
Sen. Dianne Feinstein said on Fox News Sunday, "This is something that could have an effect on national security. I think we should have been told."
FBI officials say they did not notify lawmakers or the White House because no national security issues were involved. On CBS This Morning, Retired General Richard Myers spoke to whether the President should have been told about the probe when it started last summer.
Ret. Gen. Richard Myers said on CBS This Morning, "In my view, that would not have been unusual. In the Department of Defense that's what would have happened actually."
Petraeus stepped down after admitting to an extramarital affair. His alleged mistress, Paula Broadwell, made this comment about the general while promoting the biography she wrote about him in February. She says on YouTube, "I'm not in love with David Petraeus, but I think he does present a terrific role model for young people."
General Petraeus was scheduled to testify before Congress this week about the deadly attack on the US consulate in Benghazi, Libya. His former deputy - and acting CIA director Mike Morell will testify instead.
But lawmakers say Petraeus could still be called to testify in the future. Sen. Lindsey Graham said on Face the Nation, "I don't see how you can find out what happened in Benghazi before, during, and after the attack if Petraeus doesn't testify."
CBS News has learned that General Petraeus visited Libya last month, and called several members of Congress the week before he resigned to give them his assessment of the attack.
The FBI started investigating Petraeus after receiving complaints from a woman who said Broadwell was sending her harassing emails.
