Carly Fiorina says she is not going to be shy about taking on Donald Trump in Wednesday night's CNN debate.
"Mr. Trump's going to be hearing quite a lot from me," she told CNBC's John Harwood in a pre-debate interview.
Trump has directed some of his most personal attacks at the former HP chief. He has poked fun at her physical appearance and suggested that her voice gives him "a massive headache."
Fiorina, the only woman in the GOP field, noted that Trump's insults to her have taken a different tone than his slams at male Republican contenders.
"Donald Trump has said many things about other candidates, but he has not talked about their appearance," she said.
Fiorina also said she will be happy to discuss Trump's business record on Wednesday, including taking aim at the fact that the real estate mogul has admitted that he inflated the value of his holdings.
"In the business I was in, we had to report our results publicly, as you well know, in excruciating detail, quarter after quarter after quarter," she told Harwood. "And if I misrepresented those results or those projections I could be held criminally liable. If I had done it, I could have gone to jail."
