Fox News host and Republican debate moderator Megyn Kelly took U.S. presidential hopeful Donald Trump to task on Thursday for making disparaging comments about women in the past, and The Donald's response was less than apologetic.

"You've called women you don't like fat pigs, dogs, slobs and disgusting animals," Kelly said. She went on to say Trump once said he wanted to see a Celebrity Apprentice contestant on her knees.

Trump responded that America is too politically correct and the country doesn't have time for it. 

"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," he said. 

Trump takes jab at Rosie O'Donnell

Trump also said he didn't call all women names, "Only Rosie O'Donnell."

O'Donnell then tweeted, "Try explaining that 2 ur kids."

Twitter noticed the heated exchange. 

Many responded with a virtual pat on the back to Kelly for her line of questioning. 

While Kelly's fierce personal questioning was applauded by many, some thought sticking to straight political issues was a more meaningful place to start.
