Carly Fiorina took direct aim at Democratic presidential candidate Hillary Clinton while on the campaign trail in Iowa, and said the Republican Party needs a tough presidential nominee ready to confront Clinton.

Despite sharing the stage at the Iowa Growth and Opportunity forum with more than a half dozen other Republican candidates, Fiorina focused on Clinton and her recent testimony before the House Select Committee on Benghazi.

"We need a fearless nominee who will throw every punch at Hillary Clinton; who will point out to the American people over and over again that she lacks a track record of accomplishment; that she is not trustworthy; and yes, indeed, she lied about the death of four Americans in Benghazi, Libya," Fiorina told the crowd. "And we have her red-handed."

Fiorina said anyone who watched the Benghazi hearings knows that Clinton told her daughter that she knew the firefight on Sept. 11, 2012, was a terrorist attack and chose to publicly proclaim blame on a video. The businesswoman turned GOP presidential candidate then sought to distinguish herself from Clinton and portray her candidacy as uniquely capable of combating Clinton's advances.

"If Hillary Clinton is forced to run on her track record of accomplishment, or lack thereof, if she is forced by a nominee to confront her lies, on that ground ladies and gentlemen, we will win this election," Fiorina said. "I tell you the one thing I will never do. I will never ask for your votes or your support because I am a woman, although I am proud to be one. I will ask for your votes, and your support, and your prayers because I am the most qualified candidate to beat Hillary Clinton and to become president of the United States."

Fiorina rose to fifth in the Washington Examiner's most recent GOP presidential power rankings issued after Wednesday's debate on CNBC.
