What Republicans need to do is check whether with Miller or his predecessor received a retirement package.
I'm pretty sure he will get a nice package since he is now saying that he is leaving because his term is up in June .... not because Obama asked him to resign. So it doesn't sound like he is resigning at all .... He just won't be seeking another term with the IRS. I'm sure the Prez with a fez knew this all along and just staged today's event for public and media consumption.
