For him it’s another display of narcissistic power. It basically says “look at how blatantly I lie to you, but I’m so powerful that you’ll never hold me to account for it.” The moron thinks he’s the smartest thing in the room, but since he cannot look outside in, he cannot comprehend what a clown he looks like.

Same thing with him phoning in that he’s 6’3″ and 215 at his arraignment, instead of being told to get on the scale. And he’s not completely wrong, because we keep letting him do it.
