Roger Ailes put Glenn Beck on his network and fought to keep him on even when affiliates were scared off by harassed advertisers and (no doubt) the White House leaned. The show was is a ratings free-fall as Beck got weirder by the day.
I don't know why it isn't enough for Beck to state publicly that WH intimidation had NOTHING to do with his cancelation. Just like it had nothing to do with the cancelation of Rush's TV show after many affiliates dumped it into 3:00am and 4:00am time slots.
