Olbermann Names Michael Calderone One Of Worst Persons In The World (VIDEO)

Keith Olbermann named Politico reporter Michael Calderone one of his "Worst Persons In The World" for falsely reporting that it was Olbermann who audibly uttered "oh god" as MSNBC cut to Governor Bobby Jindal for his rebuttal to President Obama's address. In fact, it was Chris Matthews who said it, something that Calderone eventually corrected, but evidently not to Olbermann's satisfaction. The MSNBC host accused Calderone of pretending to have gotten it right all along.

Calderone disputes this, but apologized to Olbermann nevertheless, saying "It's never all right in journalism to assume."
