Arianna Huffington has reportedly been BANISHED by NBC news—including MSNBC!—because her new book savagely criticizes NBC political honcho Tim Russert. Keith Kelly reports: "Sources said that Huffington was at a dinner in the home of Barbara Walters on Tuesday night when she heard that word had come down from on high that she no longer appear on NBC or MSNBC, where talk show hosts Keith Olbermann, Joe Scarborough and Dan Abrams were all interested in booking her." NBC's Phil Griffin claims to not know anything about it. We'd argue Arianna was just playing up a rumor she heard to publicize her book, but Griffin adds: "I know some people have issues with her as a guest, but it has nothing to do with the book." Say what you will about Arianna, but she's generally a great guest. So we'll take that as a confirmation. Arianna used to appear on Olbermann's and Dan Abrhams' shows fairly regularly, but her media schedule shows no forthcoming appearances. [NYP]

CNN has apparently banned some of its most recognizable analysts from its campaign coverage. James Carville and Paul Begala—CNN's top Democratic analysts, both of whom achieved political fame in Bill Clinton's 1992 campaign, and both of whom support Hillary—were suspended from commenting on the presidential race sometime in December. And no one noticed!
