Here is the text from that part of the interview on hannity
Let's start with what he said. Here's the exchange between Hannity and Trump (bolding is mine):
Hannity: Is there a process " what was your process to declassify?
Trump: There doesn't have to be a process, as I understand it. You know, there's " different people say different things, but as I understand there doesn't have to be.
If you're the president of the United States, you can declassify just by saying, it's declassified. Even by thinking about it, because you're sending it to Mar-a-Lago or to wherever you're sending it.
And there doesn't have to be a process. There can be a process, but there doesn't have to be. You're the president, you make that decision. So when you send it, it's declassified. We " I declassified everything.
Now, I declassified things, and we were having a lot of problems with NARA. You know, NARA is a radical left group of people running that thing, and when you send documents over there, I would say there's a very good chance that a lot of those documents will never be seen again.
There's also a lot of speculation because of what they did, the severity of the FBI coming and raiding Mar-a-Lago. Were they looking for the Hillary Clinton emails that were deleted, but they are around someplace?
