In the first of two Fox News Republican presidential debates, Carly Fiorina had some strong words for current GOP front-runner Donald Trump.

Fiorina pointed out that she didn't receive a phone call from Bill Clinton before declaring her candidacy, unlike Trump.

"Maybe it's because I hadn't given money to his foundation or donated to his wife's Senate campaign," Fiorina said.

The former Hewlett-Packard CEO said that since Trump has changed his mind on amnesty, health care and abortion, she would ask him about the principles by which he would govern.

Tune in to the primetime debate, moderated by Bret Baier, Megyn Kelly and Chris Wallace, at 9p ET to see if Trump has a response to Fiorina's critique.

When it's all over, join Megyn on "The Kelly File," followed by a live "Hannity" at midnight ET.
