A super PAC backing 2016 Republican presidential candidate Carly Fiorina released an anti-abortion campaign ad to support Fiorina's allegations of an undercover Planned Parenthood video that purportedly shows employees talking about harvesting the brain of a fully formed fetus.

During the second GOP debate, Fiorina petitioned the president to shut down Planned Parenthood over an egregious video featuring "a fully formed fetus on the table, its heart beating, its legs kicking, while someone says we have to keep it alive to harvest its brain."

Following her comments at the debate, Planned Parenthood released a statement saying the former Hewitt-Packard CEO's remarks are "totally false" and that no video of the kind exists, reports Jezebel.

In response, CARLY for America created its own version of the video that Fiorina had described in a campaign ad titled "Character of our Nation." However, critics say that the ad features a mash-up of the videos already released by the Center for Medical Progress.

Critics of the ad note that it is not entirely clear where that photos and video footage was shot, although most of the gruesome anti-abortion images were derived from Grantham Collection, a group purposed to end "abortion-related violence." It provides no information about where the photos and videos were taken, nor does it suggest that they were taken at a Planned Parenthood.

"There is no polite way to say this: Carly Fiorina is lying. There is no video showing anything like what she claims. It's just totally false, no matter how many times she repeats it," said Planned Parenthood spokesperson Eric Ferrero on Wednesday.

Planned Parenthood is now asking Fiorina's campaign to remove the video, noting that one photo actually portrays "a Pennsylvania woman's stillborn son, which was used without her permission and falsely passed off as an aborted fetus in an earlier video" by the Center for Medical Progress. The women's health group also claims that the video of a kicking fetus comes from "the discredited Grantham Collection, an old anti-abortion archive based in Florida" and that the audio splices together three different CMP stings.

"This fake video doesn't show what you have claimed," Dawn Laguens, executive director of the Planned Parenthood Action Fund, writes in the letter to Fiorina, according to The Washington Post. "Simply put, the video you described at the debate does not exist, and the video you're now asking people to watch is not what you claim it is. This fraudulent video is beneath a serious candidate for the presidency, and you should take it down immediately."

Fiorina's deputy campaign manager, Sarah Isgur Flores, struck back, saying, "Carly is a cancer survivor and doesn't need to be lectured on women's health by anyone," said "Over their long and factually incorrect letter, Planned Parenthood doesn't and can't deny they are butchering babies and selling their organs. This is about the character of our nation."
