Hillary Clinton's people get her primo "surprise" guest spot on David Letterman show.

Go Hil go!
Access Hollywood:
Presidential candidate Hillary Clinton will be a surprise guest when David Letterman returns to the air tonight.
Worldwide Pants, which produces “The Late Show With David Letterman,” reached a deal over the holiday period with the WGA, which today sees his writers returning to work.
Earlier it was announced that Robin Williams was Letterman’s first guest, but now, Access Hollywood has exclusively learned that Clinton will also make an appearance. As previously announced, Lupe Fiasco will be the musical guest on the show.
