MARK HALPERIN: I asked him about it on Friday and he said he'll be happy to do it after the audits are done. We've been through it, around and around on this with him. But he could release it if he wanted to.

This is a matter of tradition and transparency that needs to be upheld. And every time someone interviews Donald Trump, that should be a question that they ask.
