Update: Coverage of the second Republican debate.

Thursday night's Republican debate, Fox News debate moderator Megyn Kelly asked Donald Trump about his misogynistic comments about women's looks.

"You’ve called women you don’t like, ‘fat pigs,’ ‘dogs,’ slobs, and disgusting animals. … It was well beyond Rosie O’Donnell. 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?" Kelly asked Trump.

Trump, unsurprisingly, was less than apologetic.

But he does have a long history of insulting women — on Twitter and elsewhere. Here's a bit more detail on his history.

"Fat pig"

Rosie O'Donnell, in 2006, in the middle of a feud between Trump and O'Donnell. According to Fox News at the time:

Trump said O'Donnell was "a huge liability" for "The View," the ABC show she co-hosts. He told FOX News that the only thing she had going for her was a "nice girlfriend," referring to Kelli O'Donnell. Trump referred to Rosie O'Donnell as a "big, fat pig" when imagining how her partner had announced to her family that she was involved with the comedian. "Can you imagine the parents of Kelli ... when she said, 'Mom, Dad, I just fell in love with a big, fat pig named Rosie'?" he said. "Can you imagine the expression on their face?"

"Slobs"

Also Rosie O'Donnell, whom Trump seems to have insulted to everyone he could find. From Gothamist:

In response, Donald sat down with "The Insider" and told us exactly how he feels about "The View" co-host. "Rosie O'Donnell's disgusting both inside and out," he said. "You take a look at her, she's a slob. She talks like a truck driver, she doesn't have her facts, she'll say anything that comes to her mind. Her show failed when it was a talk show, the ratings went very, very, very low and very bad, and she got essentially thrown off television. I mean she's basically a disaster."

Trump does seem to use "slob" as a somewhat gender-neutral insult, as in this 2014 tweet seeming to refer to BuzzFeed reporter McKay Coppins:

A dishonest slob of a reporter, who doesn't understand my sarcasm when talking about him or his wife, wrote a foolish & boring Trump "hit" — Donald J. Trump (@realDonaldTrump) February 15, 2014

"Disgusting"

Trump reportedly had a "meltdown" when a lawyer requested a break from a deposition in order to pump breast milk, according to the New York Times:

When the lawyer, Elizabeth Beck, asked for a medical break, Mr. Trump and his lawyers objected, demanding that the deposition continue. Ms. Beck said it was urgent — she needed to pump breast milk for her 3-month-old daughter, and she took the pump out to make her point. Mr. Trump erupted. "You’re disgusting," he told Ms. Beck, in a remark that is not disputed by either side. He then walked out of the room, ending the testimony for the day.

"Animal"

O'Donnell again, also in 2006, according to People:

To the FOX News Channel, he said: "(View executive producer) Barbara Walters, in my opinion rues the day she put that animal on her show."

"Dogs"

Trump once sent a copy of a column from the New York Times's Gail Collins to the columnist in the mail, with "Face of a Dog!" written on her picture, Collins wrote:

During one down period, I referred to him in print as a 'financially embattled thousandaire,' and he sent me a copy of the column with my picture circled and 'The Face of a Dog!' written over it.

"On her knees"

This happened on Celebrity Apprentice: All-Stars in 2013.

As VH1 wrote:

LaToya Jackson, Bret Michaels, and former Playboy Playmate Brande Roderick were in the boardroom, presenting their arguments as to why they shouldn’t be fired to the brainless triumvirate of Donald Trump,Ivanka Trump and Piers Morgan. Bret explains to his eventual executioners that, at one point, Brande "got down on her knees and passionately said, ‘I want to do this.'" The innuendo was too thick for a goon like Donald Trump to let the statement simply slide. "Excuse me, you DROPPED to your knees?", Trump directs towards Brande. "Yes," Brande responds. It’s at this point that you can see the wheels of Trump’s dirty mind turning, verrrrrrry slowly yet very surely. A full six seconds, which is an ETERNITY of time in the rapid-paced world of reality television editing, expire before Trump responds, "It must be a pretty picture. You dropping to your knees."

Trump's response

"Megyn, if you don’t like it, I’m sorry," Trump said in response to all this. Then he implied that he might insult her too:

"I’ve been very nice to you, although I could probably maybe not be based on the way you have treated me."
