Trump wants his message to get out. He is accessible to the industry. Which industry organ has access should be irrelevant, they all claim to be objective. The reason they are complaining is that campaign duty and WH duty are plum jobs. Perks like you can't imagine.
At any rate, by the press's own standard, banning one or more outlets makes no difference, because they are all objective. Trump is entitled to a different point of view, and by the press's own standard, banning one or more outlet makes no difference in the coverage, because all of them are objective.
Plus, the "banned" outlets spend more time talking about Trump than the other outlets.
As far as I know, Trump is still denying Ailes is helping. Plus, their friendship exists independently and is available post-November, no matter what.
