"When Paul Ryan says his priority is to make sure, he's just being America's accountant and trying to you know be responsible, this is the same guy that voted for two wars that were unpaid for, voted for the Bush tax cuts that were unpaid for, voted for the prescription drug bill that cost as much as my health care bill -- but wasn't paid for. So it's not on the level."
