"I was a liberal mole at Fox News: From Bill O’Reilly to Roger Ailes, here’s all the inside dope"
For example, some unlucky guests were banned for life from every show on the network, a result of a diktat from the Second Floor. Comedian Bill Maher, once a semi-regular guest on “The Factor” and some other Fox shows, made too many cracks about Sarah Palin over the years, raising the ire of a powerful female VP who banned him from our air and demanded that all Fox-affiliated websites refer to him only as “Pig Maher.”
Sometimes entire organizations were given lifetime bans. The website Politico wrote something a few years back that rubbed Roger the wrong way (we were never told what exactly the transgression was) and word went out to all the shows: No more Politico reporters as guests. Also, any anchors who mentioned the site on air had to use the phrase “left-wing Politico” — an absurd designation for a publication that usually played it down the middle.
