Simon called Romney's refusal to release more of his tax records absurd.

"I can’t get over the absurdity of this moment, honestly: Hey, I never paid less than thirteen percent. I swear. And no, you can’t examine my tax returns in any more detail," Simon wrote, in Romney's voice. "But I promise you all, my fellow American citizens, I never once slipped to single digits. I’m just not that kind of guy."

"This republic is just about over, isn’t it?" Simon concluded.
