I hadn't actually seen this moment with Newt Gingrich and John King until I was filing through some old Daily Show segments. I don't really understand why reporters allow themselves to be fodder for this sort of thing. I think the worst part is King's backpeddaling attempt to blame the question (about Newt's previous marriage) on someone else, which allowed Newt to go into nuclear faux-outrage mode.
