Originally a comment by Claire on It’s not optional.

My husband and I have been talking about what an interview between Mueller and Trump would look like. If this were literally any other politician, they would answer carefully, with narrow answers, resist the urge to elaborate, and if possible, try to answer the question they want to answer rather than the one they were asked. And if needed, plead the fifth.

I think Trump is constitutionally incapable of all of these things, including pleading the fifth. Because once you plead the fifth, you have to shut up. That requires considerable self-control, because social animals that we are, most people are uncomfortable to sit in silence. Sitting in silence letting suspects fill the room with noise is what good investigators do.

Trump has some of the poorest self-control I’ve ever seen in an adult, and you know he’d be “oh I plead the fifth on that question because you know this a made up story and Comey, what a liar that guy was, he was part of the Deep State… you know the Deep State is working to destroy me because they’re all Democrats and they’re mad because Crooked Hillary should have won, they said I couldn’t get to 270 and boy were they wrong and there’s no collusion because you know, this Russa thing is a hoax and I never pay for hookers I don’t need to do I look like a man who needs hookers…then Putin said I can fix this for you because it’s a rigged system, rigged system that’s what I call it, have you ever heard that term before I came up with it myself I like the sound of it, and you know, this is all a plot by Democrats and your team is full of Democrats…” etc etc ad nauseum.

And Mueller will smile and nod and write everything down.
