WALLACE: The president has changed his story repeatedly about whether or not he knew about hush money. Here is what he said on Air Force One -- the president said on Air Force One this April, eight months ago. . . . The president said he doesn’t know anything about any payments, but in one of those tapes that you’re talking about where Cohen surreptitiously taped the president -- this is back in September of 2016 -- here are the president and Cohen discussing a potential -- . . . . So which is it? Did the president know about the hush money payments or not?

GIULIANI: Chris, there’s an intervening event that you’re not talking about. I know this really well because I got criticized for revealing this when I first came into the case. Nobody really understood why I was doing it. . . .

When I first came into the case, we went through the whole case. The president saw some notes and documents, thought about it, and I went out and said, no, there was an intervening conversation after the payments took place and before the revelations you're talking about on Air Force One.

The president did talk to Cohen or to people in between and they arranged to reimburse Cohen. This was after the payment was made, after it was over, after the campaign was over. . . .

WALLACE: They're talking about a conversation, sir, in September of 2016 during the campaign. The president is clearly aware that David Pecker, the head of "National Enquirer" had paid off Karen McDougal and they're talking about reimbursing McDougal --

GIULIANI: Well, you know, that's --

WALLACE: -- or reimbursing Pecker for that payment.

GIULIANI: But there's a -- there's a big difference here. That was a - that was a conversation he was asked, middle of the campaign, I was with him back then in the middle of the campaign, he's working 18 hours a day. I wasn't able to remember a lot of things that happened in September of 2016. He was asked it one time.

When he sat down with his lawyer and went through it in great detail and saw things that could refresh his recollection, we immediately corrected it.

Nobody pushed us, nobody found it, we found it. And we corrected it and I got criticized like crazy for doing it. . . .

WALLACE: You're moving shells around on me. Either it happened or it didn't happen.

GIULIANI: But that's what lawyers do all the time. You argue in the alternative. I'm telling it --

WALLACE: But I’m asking you for the truth, sir.
