//Did he also say that no prosecutor would resort to a sworn affidavit or submitted written questions (as the responses would be just the lawyers speaking)? //

Wait...what? I’m no expert on such matters but isn’t this precisely what HRC did?

If imagine, as POTUS, he has a lot of leeway as to what he’s willing to do or not do. Would he even be compelled to react to a Grand Jury subpoena? I’d so, whilst I know an attorney cannot be in the room it is my understanding his lawyer can sit out of the room and Trump can literally walk out after each question and consult.
