Despite our lengthy reports on MSNBC’s inner workings, Jossip continues to get asked back to appear on the network. (Okay, yesterday’s David Gregory item might have officially killed our welcome.) But Arianna Huffington, here with some familiar faces, thinks she’s been banned from 30 Rock thanks to her dubbing Meet the Press host and D.C. bureau chief Tim Russert as “EZ Pass,” thanks to his letting Washington’s elite get a free pass on his Sunday chat show.

Keith Kelly’s “sources” (Huffington herself?) claim the blog diva got the news of her blackball on Tuesday night while she was dining at Barbara Walters home, though NBC News SVP Phil Griffin claims, “I haven’t seen the book. I don’t know anything about it.”

Then again, Huffington does have a new book, Right is Wrong, to promote, and what better way to get the word out than fluff up a story like this? Sure, if true, potential bookings on Countdown and Hardball are out, but perhaps she’ll get a nice rant-laden plug on The O’Reilly Factor.
