Carly Fiorina said Monday that Donald Trump is in the right to attack Bill Clinton, but noted that method is not the way to beat Hillary Clinton, who will play the "woman card" every chance she gets, according to the former Hewlett Packard CEO.

"Of course Bill Clinton’s fair game. He’s a former president," Fiorina said on "Fox and Friends" Monday morning, The Washington Times reported. "And as I recall, Donald Trump threw George W. Bush under the bus way back in September, but you're not going to beat Hillary Clinton by attacking Bill Clinton."

Fiorina was asked about the Clintons because Donald Trump engaged in a war of words in interviews and on Twitter that included knocking Bill Clinton for his infidelity last week, as HNGN.com previously reported.

The Clinton-Trump battle started a week ago when Trump said Clinton got "schlonged" in the 2008 Democratic primary against then-Senator Barack Obama. Hillary Clinton's reaction to Trump's comments was to suggest he has a "penchant for sexism."

Fiorina, who had a mini-surge among the Republican field after going head-to-head with Trump in the second GOP debate before sliding in the polls again, took issue with Clinton's characterization.

"Hillary Clinton, first of all, calls everybody a sexist and that's not fair game," Fiorina said on Fox News Monday, CNN reported. "She called Bernie Sanders a sexist because he criticized her. She's going to play that card, we need to be realistic, and of course she's going to talk about the Republican war on women, which doesn't exist."

Fiorina also made the case for why she should be the first woman to become president at a moment when many Americans are saying the time is ripe for it.

"Hillary Clinton wants to talk about the historic nature of her candidacy, she wants to talk about being first woman president and there are people out there - lots of people, men and women - who think its time for a woman president," Fiorina said, according to Politico. "My message to them will be, 'Look, how about an honest woman, a competent woman? How about a qualified woman?' But I'm never going to ask for people's support because I'm a woman. I'm going to ask for their support because I'm the most qualified candidate to beat Hillary Clinton and to do the job."
