Anderson Cooper dressed down President Donald Trump for his out-of-the-blue personal attack on CNN colleague Kaitlan Collins Wednesday. (Watch the video below.)

In the process he arrived at the essence of Trump’s “completely unwarranted” antics: “This doesn’t happen to men.”

“I’m not asking Kaitlan about this because she’s got actual work to do, and she doesn’t need to be answering questions about this kind of behavior,” Cooper said. “That’s the president of the United States, a nearly 80-year-old man who has no problem commenting on her physical appearance and telling her she needs to smile. That doesn’t happen to men. No one’s ever said that to me in an office setting. She was there like every other journalist doing her job, standing around with a bunch of non-smiling men, by the way, all behind her. I don’t know if you saw that. She gets singled out.”

Earlier Cooper played a clip of the confrontation when the president veered sharply from answering someone else’s question about the apparently shelved so-called “anti-weaponization” fund and zeroed in on Collins, who stood silently in the Oval Office.

“CNN’s a very corrupt organization, but with a corrupt reporter standing right there,” Trump said. “Never smiles. ... She’s a young, beautiful woman. Never smiles. I never see a smile on her face. I see her standing there with hatred in her eyes. She has hatred because we have borders, because we have a strong military, because we cut our taxes, because we do things that everybody wanted.”

Cooper played a supercut of Trump’s obnoxious diminishing of Collins and other women reporters, asking journalist Tara Palmeri about it.

“It’s just bizarre that this is something he does over and over and over again,” the host said. “... And I think people do it to women all the time.”

“What you are seeing is a day in the life of a woman,” Palmeri replied. “She’s a powerful woman, and he’s objectifying her, and he’s using a misogynistic comment about her appearance to belittle her.”
