What Susan Rice Actually Said
It is pretty clear that when she went on Meet the Press, she said that there was an FBI investigation and that information was still coming in about the attack in Benghazi. I think any reasonable person can see that there was no effort to cover anything up. When the facts were in and confirmed the government announced it was a terror attack.
The nonsensical (and probably fake) outrage that McCain and Graham have been expressing makes them look like complete dolts in my opinion. Susan Rice will be confirmed as Secretary of State if the President wants her to be confirmed. If she is derailed by Republicans, it will just be further evidence that they have gone off the deep end and are drowning into oblivion.
