There is a good deal of confusion surrounding the “Free Speech Week” set to occur later this month at the University of California, Berkeley.

The school says event organizers failed to meet key deadlines, and multiple speakers allegedly scheduled to participate say they never agreed to do so. After a press release sent on behalf of MILO, Inc. last week included them on the list of headline speakers, both Charles Murray and Heather Mac Donald said they had never even been contacted about appearing.
