"So, the last time I was at the hospital, well, probably a year ago, a little less than a year ago, I asked the doctor. I said: 'Is there some kind of a cognitive test that I could take? Because I have been hearing about it, because I want to shut these people up.'

"They're -- they're fake news. They make up stories. I mean, like, I will do an interview with you. You -- I didn't say you can ask me about this, you can't -- I say, ask me anything. I did one with Chris Wallace.

"He was nice enough to say. He said, I just want to tell the audience there was no question that's off bounds, OK? And he's a tough cookie. And it was a good interview. I liked it. I enjoyed it. And it was good.

"But I didn't say, you can only ask this. You can only -- we have to be sharp. If you're in the office of the presidency, we have to be sharp.

"So, they were saying all these different things. It was going all over, whichever stuck. None of it stuck, fortunately. But one of the reasons it didn't is that I took a test. I said to the doctor -- it was Dr. Ronny Jackson -- I said: 'Is there some kind of a test, an acuity test?'

"And he said: 'There actually is.' And he named it, whatever it might be. And it was 30 or 35 questions. The first questions are very easy. The last questions are much more difficult, like a memory question. It's like, you will go person, woman, man, camera, TV.

"So, they say, could you repeat that? So, I said, yes. So, it's person, woman, man, camera, TV. OK, that's very good.

"If you get it in order, you get extra points. If you -- OK, now he's asking you other questions, other questions. And then 10 minutes, 15, 20 minutes later, they say, remember the first question, not the first, but the 10th question? Give us that again. Can you do that again? And you go, person, woman, man, camera TV.

"If you get it in order, you get extra points.

"They said, nobody gets it in order. It's actually not that easy. But, for me, it was easy.

"And that's not an easy question. In other words, they ask you to -- they give you five names, and you have to repeat them. And that's OK. If you repeat them out of order, it's OK, but you know, it's not as good.

"But then, when you go back, about 20, 25 minutes later, and they say, go back to that question -- they don't tell you this. Go back to that question, and repeat them. Can you do it? And you go, person, woman, man, camera, TV.

"They say: 'That's amazing. How did you do that?'

"I do it because I have, like, a good memory, because I'm cognitively there."

This isn't the first time Trump has mentioned taking a test to measure his cognitive abilities. In an interview with Fox News' Sean Hannity -- notice a pattern? -- earlier this month, he said this:

"I actually took one when I -- very recently, when I -- when I was -- the radical left were saying, is he all there? Is he all there? And I proved I was all there, because I got -- I aced it. I aced the test. ... I took it at Walter Reed Medical Cen
