First, Fire and Fury should not be taken as a serious information source. It’s written by an individual who might rightly be called the Donald Trump of journalism, given his lack of adherence to norms and past record of playing fast and loose with factual accuracy. He’s already been caught getting into the White House on false pretenses.
Second, it’s not as if Trump or anyone in his regime has much ground to stand on when it comes to complaining about such things.
Third, there is no Gorilla Channel. That’s a hoax. It wasn’t believable to start with:
I had never heard of any such thing, yet Trump is supposed to have had access to it in Trump Tower (but not the White House?). If it were a cable channel, you’d expect it to be available pretty much everywhere there is cable. If Washington, DC has an inferior cable system that doesn’t carry it, it wouldn’t be that hard to install an earth station at the White House to receive it.
They set up “a hastily-constructed transmission tower on the South Lawn” to broadcast it? Really? That tower would have attracted the attention of photographers; surely someone would have noticed it. And why erect a transmission tower for cable TV? Far simpler and easier to just modulate a signal and inject it into the coax. If over-the-air transmission is for some reason desired, a tower isn’t needed for a low-power signal, anyhow. This wouldn’t need to reach farther than a few rooms in the White House; it would be a simple matter to put an ultra low-power transmitter in a closet somewhere.
Fourth, the book’s general premise, that Trump is totally unfit for the job he finds himself in, is no big surprise and was obvious already.
