Ouch.

Donald Trump scolded media big shots during an off-the-record Trump Tower sitdown on Monday, sources told The Post.

“It was like a f–ing firing squad,” one source said of the encounter.

“Trump started with [CNN chief] Jeff Zucker and said ‘I hate your network, everyone at CNN is a liar and you should be ashamed,’ ” the source said.

“The meeting was a total disaster. The TV execs and anchors went in there thinking they would be discussing the access they would get to the Trump administration, but instead they got a Trump-style dressing down,” the source added.

A second source confirmed the fireworks.

“The meeting took place in a big board room and there were about 30 or 40 people, including the big news anchors from all the networks,” the other source said.

“Trump kept saying, ‘We’re in a room of liars, the deceitful dishonest media who got it all wrong.’ He addressed everyone in the room calling the media dishonest, deceitful liars. He called out Jeff Zucker by name and said everyone at CNN was a liar, and CNN was [a] network of liars,” the source said.

Good for him. The old media is so biased, and their unethical practices are so blatant, that it’s about time someone got up in their grill. As long as Trump doesn’t suggest any kind of governmental action against them, there’s nothing wrong with him lambasting them for their behavior.
