Not much is the answer. Sarah Kliff from vox.com tried and tried to get a copy of what Fiorina claims to have seen. No luck. The Fiorina staffers sent her a bunch of footage but nothing matched Fiorina's Wednesday claims.
At Wednesday's debate, Carly Fiorina received thunderous applause for challenging Hillary Clinton and Barack Obama to watch a specific scene from the Planned Parenthood sting tapes. The scene, she said, showed "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."
But when asked for a citation, her campaign replied with a video that isn't from the Planned Parenthood sting tapes at all — and that still doesn't show what Fiorina said it did.
On the other hand, why should you expect her to tell the truth? Consider her audience. To paraphrase Jack Nicholson in A Few Good Men, "They can't handle the truth." Evidently neither can Carly.
