"Look I'm not going to rule out anything, we're not going to have a registry based on a religion."

This is a difficult sentence to parse and it confuses me.  

The part that says "we're not going to have a registry based on a religion" appears to rule out a registry based on religion, and to be an affirmative answer to the reporter's question.  But it follows the claim that Preibus isn't "going to rule out anything", which suggests either that Preibus isn't going to answer the question or he isn't going to rule out a registry based on religion.

Am I missing a distinction between "rule out" and "not going to have"?
