"Kim Jong Un? I can't tell you exactly. Yes, I do have a very good idea, but I can't talk about it now... I do know how he's doing, relatively speaking... You'll probably be hearing it in the not too distant future."

"I do know how he's doing, relatively speaking" — I take that to mean Trump knows relatively more than the reporter. And he has "a very good idea," which suggests he knows quite a bit more than just relatively more than the rest of us. But he "can't talk about it," though to say that is to talk about it.

So what do you think Trump knows — that Kim Jong Un is dead (or in some near-death condition)?
