It turns out Trump has been calling out CNN for its bias for years. He was doing an interview with them in 1990 when he abruptly shut it down.
Here are some details from CNN:
In the 1990 interview, Feldman pressed Trump on some of the dire predictions being made about the casino. Trump dismissed the negative outlook.
“Most analysts believe it’s going to be very successful, there are always going to be analysts who say, ‘well, maybe not, who knows?’” Trump said. “I think it’s going to be so beautiful a building, and it turned out to be so beautiful a building, that everybody is going to come. The world is coming to see the Taj Mahal.”
Feldman pointed out that other analysts he had spoken to voiced similar concerns as Roffman, causing Trump to lash out at the reporter.
“You aren’t going to talk about positive people. You’ll talk about the negative. You want to talk about the negative.”
After more back-and-forth about the tone of Feldman’s questions, Trump announced the interview was over.
“Do the interview with somebody else. Really. You don’t need this. Do it with somebody else. Have a good time. Frankly, you’re a very negative guy, and I think it’s very unfair reporting. Good luck.”
