Milo Yiannopoulos speaks on campus in the Mathematics building at the University of Colorado in Boulder, Colo. Right-wing provocateur Yiannopoulos was trying to clarify past comments on relationships between boys and older men after a conservative site posted a collection of edited video clips that set social media abuzz. After the polarizing Breitbart News editor was invited this weekend to speak at the annual Conservative Political Action Conference sparked a backlash, the Reagan Battalion tweeted video clips Sunday, Feb. 19, 2017 in which Yiannopoulos discusses Jews, sexual consent, statutory rape, child abuse and homosexuality.
