Keith Olbermann was MIA during Current TV's Iowa caucus coverage, leaving viewers to wonder if he might be in a tiff with top brass (including former Vice President Al Gore) at the network. Speculation grew when he sent the Hollywood Reporter a statement claiming "unacceptable conditions" kept him from attending. The anchor, who has a bit of a hot head reputation after being fired from FoxSportsNet and his abrupt departure from MSNBC, didn't stop there. He later started a Twitter feud with New York Times reporter Brian Stelter, claiming he tried to threaten him into commenting for the record. Stelter denied the accusations.
