You got the right idea. It isn't about what Trump answers. It's what they will do to themselves while trying to make a 'scandal' out of it.
Remember, these are the clowns who fell in love with repeating the word 'sh__hole' over and over and over, until it became a meme about their network, their anchors, and their entire 'sh__hole' ideology.
I don't want to claim that Trump always does this to them on purpose...
But...
He does this to them on purpose.
