Dicey. Could be a bit of a trap. He keeps claiming that it's trivial to bring up nonsense like whether or not he buddies around with terrorists (let's not bicker and argue about 'oo killed 'oo). It's possible that he did this intentionally to stir up debate over a trivial issue so he can 1) change the subject and 2) cry out, "See? See the sorts of silliness they're using as distractions?
I'm kind of shocked this doesn't happen more in politics.
