Lawrence O’Donnell is in dire need of a fact checker. O’Donnell, the former aide to New York Senator Daniel Patrick Moynihan, and a producer and writer for part of the run of “West Wing” on NBC, is getting his own show on MSNBC this fall. He has been a frequent guest host for Keith Olbermann, and unfortunately for him, it seems like he must be using Olbermann’s fact checkers.
