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.
