Controversial author Charles Murray's speech at the University of Michigan was met with multiple disruptions by student protesters on Wednesday, and at one point, the lights were shut off, and someone projected the words "white supremacist" on the wall.

Someone also played "The Imperial March," or Darth Vader's theme song in "Star Wars," among other disruptions, Robby Soave, an associate editor at Reason.com, tweeted from the venue.

Murray's 1994 book The Bell Curve is the subject of a great deal of controversy and debate because he argued that IQ played a role in the development of the U.S. class structure — something which his critics view as racist.

According to Soave's account, at one point, Murray said, "Men and women can be different," to which members of the audience reacted, "Racist, sexist, KKK, Charles Murray go away."

Though there was a police presence in the room, no one was removed and the event continued despite the outburts, according to Soave.

Murray was slated to talk about a more recent book, his 2012 offering, Coming Apart: The State of White America, 1960-2010, at the event hosted by the university's College Republicans chapter and the American Enterprise Institute University of Michigan Executive Council.

A number of right-wing figures have that have been scheduled to appear at universities in recent months have run into issues due to protests, including events at UC Berkeley that had been scheduled with conservative commentator Ann Coulter and former Breitbart News editor Milo Yiannopoulos.
