And this is what trump had to say about carson during the primaries:

"During the campaign, Trump said that Carson could not be trusted, and he said it in breathtaking terms:

…I don’t want a person that’s got pathological disease. I don’t want it. I’m not saying he’s got it, he said it.

This isn’t something that I’m saying, like “Oh, he’s pathological liar.” I’m not saying it! He said he’s got pathological disease. He actually said pathological temper.

And then he defined it as disease. So he said he has pathological disease.

Now. If you’re pathological, there’s no cure for that, folks.

Okay, there’s no cure for that. And I did one of the shows today. And I don’t want to say what I said. But I’ll tell you anyway. I said that if you’re a child molester, a sick puppy, you’re a child molester, there’s no cure for that. There’s only one cure—we don’t want to talk about that cure. That’s the ultimate cure. Well, there’s two, there’s death, and the other thing."

These are trumps words.
