Erik Prince, an associate of President Trump and the controversial founder of the security company Blackwater, was invited by the Young Americans for Freedom (“YAF”) at Beloit College to discuss the private sector’s contributions to national security. In response, protestors gathered before Prince arrived and created a barricade of furniture on the stage, hanging a banner on the barricade that read “Erik Prince = War Criminal.” At this point, the school canceled the event, citing safety concerns.

The college has stated that they are open to re-scheduling the event in the future.
