Donald Trump was not terribly happy with Megyn Kelly's questions Thursday night. Viewers nationwide saw that. A reminder:

KELLY: Your Twitter account has several disparaging comments about women’s looks. You once told a contestant on Celebrity Apprentice it would be a pretty picture to see her on her knees. Does that sound to you like the temperament of a man we should elect as president, and how will you answer the charge from Hillary Clinton, who was likely to be the Democratic nominee, that you are part of the war on women?

TRUMP: I think the big problem this country has is being politically correct.

(APPLAUSE)

I’ve been challenged by so many people, and I don’t frankly have time for total political correctness. And to be honest with you, this country doesn’t have time either. This country is in big trouble. We don’t win anymore. We lose to China. We lose to Mexico both in trade and at the border. We lose to everybody.

And frankly, what I say, and oftentimes it’s fun, it’s kidding. We have a good time. What I say is what I say. And honestly Megyn, if you don’t like it, I’m sorry. I’ve been very nice to you, although I could probably maybe not be, based on the way you have treated me. But I wouldn’t do that.

After the debate, an even unhappier Trump seemed to have changed his mind about that last part. Reporters in the spin room saw that.

"I thought their questions to me were much tougher than to other people, and I respect that, but I really enjoyed the evening," Trump said. "The questions to me were far tougher, and that I supposedly -- according to what everyone is telling me, and the call-ins and everything, I won. But the questions to me were not nice. I didn't think they were appropriate. And I thought Megyn behaved very badly, personally."...

"I thought it was an unfair question," said Trump in the spin room. "They didn't ask those questions of anybody else. So I thought it was an unfair question. But you know what? The answers were good, obviously, because everyone thinks I won."

He wasn't done venting. Next up: after-hours Twitter. If Megyn Kelly found some elements of his Twitter feed objectionable before the debate, the post-debate edition probably didn't do much to change that opinion.

Trump tweeted -- and retweeted other angry late-night Twitter users -- more than 30 times between roughly 2:30 a.m. and 4:30 a.m. Many of those tweets mentioned Megyn Kelly or her debate co-hosts, along with Republican pollster Frank Luntz, who ran a televised post-debate focus group on Fox Thursday night. None of them were compliments.

The final tweet of the wee hours drew some of the biggest reaction -- including a "won't someone think of the children?" moment.

With the morning, the feud shifted back to the Fox airwaves, with Trump expressing his irritation other debate questions as well -- including the first of the evening, which asked participants if they would pledge not to stage an independent run if they fail to win the GOP nomination:

"It was a little bit of a surprise to be standing up there having to justify everything," Trump said.

Noted: Donald Trump does not like surprises. Among other things.
