Michael Moore to contribute to Keith Olbermann's Current TV Countdown

Olbermann exited MSNBC in January in the middle of a four-year, $30 million contract; he signed with Current TV a month later. His had a stormy tenure at MSNBC that included a suspension over campaign contributions he made — but he helped drive viewership up while he was there. Besides hosting his show, he'll serve as Current TV's chief news officer.
