CHRIS CUOMO (HOST): You're kind of reintroducing yourself to the voters there. Is there any regret that you hold in your heart, for the conditions that people were kept in? The nature of immigration enforcement? The birtherism claims about President Obama? Things that are black marks on your record, do you have any regret, do you have any change on any of those?
JOE ARPAIO: Well, you know, Frank Sinatra says in “My Way,” “Regrets, I've had a few, too few to mention.” I would repeat that to you, but no, I have no regrets.

CUOMO: So, you think President Obama's birth certificate is a phony?
ARPAIO: No doubt about it. No doubt about it, we have the evidence. I'm not going to go into all the details. Yeah, it's a phony document.
