Megyn's revenge: Fox News host goes for the jugular forcing Trump to answer questions about his constantly changing political stances and lawsuits against his university 

Megyn Kelly and Donald Trump were reunited at Thursday night's Fox News debate.

Kelly did not ask the Republican a front-runner a question for the first 30 minutes of the debate, but when she did about his immigration policies, Trump greeted her by saying; 'Nice to be with you Megyn. You’re looking well.' 

The Fox News host was cordial, but focused all night as she forced Trump to answer questions about policy and did not allow him to speak over her like he was doing with some of the other candidates on the stage.

Kelly at one point played video examples of times Trump changed his political stances and soon after pointed out the lawsuits that had been filed against him and Trump University.

'We have a 98% approval rating, we have an A from the Better Business Bureau and people like it,' Trump said of Trump University.

Kelly immediately responded by saying; 'The rating from the BBB was a D- and it was a result of a number of complaints they received.'

She then pointed out that 'there’s a class action of 5,000 people' saying these people included 'veterans' and 'teachers.'

Kelly asked Trump a question for the first time about immigration 30 minutes into the debate 

'The plaintiffs against you are like the Madoff victims,' said Kelly at one point, before reading the opinion handed down by the US Court of Appeals, which said; '... victims of con artists often sing the praises of their victimizers until they realize that they have been fleeced.' 

'Give me break,' said Trump.

'Lets see what happens in a couple of years.'

Rubio then interjected; 'He’s making promises he has no intention of keeping… he’s trying to con people into giving them their vote, just like he conned people into giving him their money.'

Trump then changed the subject by saying the people of Florida know who not even elect Rubio as 'dog catcher.' 

Later, during a commercial break, Trump actually walked over to the moderators and handed them the new report from the Better Business Bureau on Trump University.  

Kelly also played clips that showed Trump saying he was for and against having armed troops in Afghanistan; for and against the United States accepting Syrian refugees; and saying he did and did not believe President Bush lied in order to convince Americans that the US should get involved in the Iraq War. 

'I have a very strong core,' said Trump in response to these clips.

'I’ve never seen a successful person who wasn’t flexible, who didn’t have a certain degree of flexibility.'

He later added; 'You have to be flexible, because you learn.'

Trump was forced to speak about his feud with Mitt Romney and thoughts on the Ku Klux Klan right off the bat during the debate Thursday.

Trump called Romney a 'failed candidate' who should have beaten President Barack Obama in the last election and said he had been 'disavowing the Ku Klux Klan for two weeks now.'

The questions were not asked to Trump by Kelly however, but rather the debate's other host, Chris Wallace. 

Romney came out against Trump on Thursday saying Republicans should vote for any other candidate in the primary race, Trump responded by saying Romney begged him for an endorsement when he ran for president in 2012, adding; 'I could have said, "Mitt, drop to your knees," and he would have dropped to his knees!' 

Trump also drew criticism from House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell on Tuesday over his refusal to disavow the backing of his campaign by former Ku Klux Klan leader David Duke.

Trump responded at the time by saying; 'Paul Ryan, I don't know him well, but I'm sure I'm going to get along great with him.

'And if I don't, he's going to have to pay a big price, OK?' 

Kelly was largely quiet in the beginning of Thursday's debate, with Wallace asking almost all of the questions.

The debate was also mostly a back and forth between Trump and Senator Marco Rubio for the first 30 minutes, with Trump frequently calling his opponent 'Little Marco.' 

Trump also attacked Rubio for suggesting he had small hands. 

'Look at these hands. Are they small hands?' asked Trump early on in the debate.

Kelly previously said she was not anticipating any more fights with Trump in Thursday's Republican presidential debate, and that she was preparing the same 'tough but fair' questions for him as she does for other candidates. 

'It was never personal from my point of view,' Kelly said. 

'I understand he was upset. I didn't take it personally and I certainly don't have anything against him. I find him a very fascinating person to cover.' 

Kelly said earlier this month she did not regret questioning Trump on his history of making derogatory statements about women at the first GOP debate on Fox in August. 

'I still think it was a great question. I stand by every question I asked him and he was not the only one who had tough questions. He was the only one, however, who complained,' Kelly said. 

Trump lashed out at Kelly in the press after the debate, accusing her of singling him out and then refused to take part in the most recent Fox debate ahead of the Iowa caucuses.

Reflecting on the experience, Kelly said it was 'bizarre' to become part of the news.

'He was so very focused on me that I became the story, and you never want to be the story when you're a news person, you want to be covering the story. So it was truly an Alice through the Looking Glass experience,' she said during an appearance on Good Morning America.
