From the July 20 edition of Yahoo! News' Unconventional Live:
MICHAEL ISIKOFF: How about the birther allegations about Barack Obama? Did you discuss those with Donald Trump?
ROGER STONE: Only in the sense that after learning about them, Donald Trump asked me what I thought and I said, “Well, there’s a lot of questions here.” He said, “Well, I’m going to talk about it.” Now, no one tells Donald Trump what to talk about or what not to talk about.
ISIKOFF: Did you help him on his research on that?
STONE: I did not.
ISIKOFF: Did he send private investigators to Hawaii to look into those allegations?
STONE: He said he did so I must believe that he did.
