Carly Fiorina has repeatedly torn into Hillary Clinton for her stance on abortion and says she will not let up as long as the former secretary of state defends her "extreme" position.

During a campaign event in South Carolina on Thursday, Clinton reportedly told supporters that "Planned Parenthood has been the object of such a concerted attack for so many years," and described it as "unfortunate."

The Democratic presidential front-runner reacted on Twitter to Wisconsin Gov. Scott Walker signing a ban on abortions after 20 weeks by calling the law "extreme and unacceptable."

Fiorina, however, has used the same language to describe Clinton's stance on abortion.

When asked about Walker's abortion ban during a recent interview on CNN, Fiorina immediately deflected the question and took the opportunity to blast Clinton for her position.

"It's Hillary Clinton's position that a 13-year-old girl needs her mother's permission to go to a tanning salon or get a tattoo, but not to get an abortion," she said. "It's Hillary Clinton's position that women should not be permitted to look at an ultrasound before an abortion, and yet people who are trying to harvest body parts can use an ultrasound to make sure those body parts are preserved so they can be sold."

"That, Jake, is extreme," the former Hewlett-Packard CEO told host Jake Tapper.

Fiorina has previously said her that her pro-life position has been "clear and consistent" from the time she ran unsuccessfully for U.S. Senate in California in 2010. She recently joined a number of Republican leaders who hope to see Congress pass the Pain Capable Unborn Child Protection Act, which seeks to prohibit abortions after 20 weeks of pregnancy based on evidence that fetuses can survive outside the womb and are capable of experiencing pain at that period of gestation.

The only female candidate in the GOP does support legal abortion in cases of rape and incest, saying her views are more in line with Americans who "now believe that abortion for any reason at all, to be paid for by taxpayers, after five months is an abomination."

In her comments about the Planned Parenthood controversy, Clinton avoided condemning the behavior of both the organization's employees while instead referring to the apology issued by the Planned Parenthood itself. At the same time, Fiorina called the video footage "depraved."

"The casual nature with which these people are talking about fetuses and tissue and specimens, I tell you what — if a woman was looking at that ultrasound at that same stage in her pregnancy, the doctor would not be talking about fetuses or specimens or tissues," she said. "They would be saying, 'Look at your baby's heartbeat, look at your baby's eyes, look at your baby's organs.'"

Fiorina has developed a reputation as one of Clinton's biggest foes in the current field of presidential candidates due to her fearless attacks on the Democratic candidate on women's issues and transparency. Recently, she urged fellow Republican candidates to assist her in delegitimizing Clinton's campaign rather than continuing to attack each other.
