It’s one of the weirder things Jordan Klepper has heard at Trump rallies: Democrats are drinking the blood of children to get their daily adrenochrome fix. What is adrenochrome, and how did Hillary Clinton get involved? Jordan sits down with Matt Gertz, Senior Fellow for Media Matters for America and Elise Wang, an assistant professor at California State University, Fullerton. Together, they unravel this conspiracy theory that begins in the Middle Ages, pops up in the 2016 election, and makes its way to the non-existent basement of a Washington D.C. pizza shop.
