WALLACE: Mr. President … some people I think are worried whether or not — the decision whether or not, how to handle the [Hillary email] case, will be made on political grounds, not legal grounds. Can you guarantee to the American people, can you direct the Justice Department to say, “Hillary Clinton will be treated as the evidence goes — she will not be, in any way, protected”?
OBAMA: I can guarantee that. And I can guarantee that not because I give Attorney General Lynch a directive, [but because] that is institutionally how we have always operated. I do not talk to the attorney general about pending investigations. I do not talk to FBI directors about pending investigations. We have a strict line and always have maintained it.
WALLACE: So, just to button this up —
OBAMA: I guarantee it.
WALLACE: You —
OBAMA: I guarantee that there is no political influence in any investigation conducted by the Justice Department, or the FBI, not just in this case, but in any case.
WALLACE: And she will be —
OBAMA: Full stop. Period.
WALLACE: And she will be treated no different —
OBAMA: Guaranteed. Full stop. Nobody gets treated differently when it comes to the Justice Department, because nobody is above the law.
WALLACE: Even if she ends up as the Democratic nominee?
OBAMA: How many times do I have to say it, Chris? Guaranteed.
