Hillary Clinton says "all" the information has been provided to make a decision on Benghazi

In an interview with Robin Roberts, Hillary Clinton was asked whether she thought the Benghazi investigation should continue. She, of course, said no:

"I mean, of course there are a lot of reasons why, despite all of the hearings, all of the information that’s been provided, some choose not to be satisfied and choose to continue to move forward. "

So, is there a "quota" on how much information is provided to be considered "all"? If emails are still coming out showing more information pertinent to the case, when is it right to say "all" the information has been provided? But, then again, it doesnt make any difference to Hillary, anyway.
