@mystery-ak Trump must not answer Mueller's questions in person. I believe Trump, due to a mental disorder, does not know truth from lying. I think he believes what he is saying at the moment is the truth. The next day, he will say something entirely different about that subject, and will believe THAT is the truth. He never admits he was wrong in something he said, because he doesn't recognize he WAS wrong.
A visual example: He says he had more people at his inauguration than any in history, more than Obama. There are pictures of the mall from both inaugurations and it is evident many more were there for Obama. He has access to those photos, but still says he had more than any other president. He cannot believe, even with visual evidence, what he said was wrong.
He will lie if he has to answer questions in person, and not know he is lying. Think about it - he has been found to be lying many hundreds of times in the past year. Why would one do that? Because the person does not know it was a lie - the person every time thinks it is the truth.
If he answers Mueller in person, he will likely get himself impeached for lying under oath.
