A prominent civil rights activist and academic has cancelled a speech at the University of Illinois because of the school's decision to rescind a job offer to a Native American studies professor.

Cornel West said Wednesday that he will not speak at the Urbana-Champaign campus because of the dispute between the university and Steven Salaita. West was scheduled to deliver a lecture in April.

He called the university's decision to rescind the job offer "a moral scandal."

Salaita was offered a job starting in August 2014. The university withdrew the job offer over a series of sometimes profane, anti-Israel Twitter messages.

Salaita has sued in an effort to force the university to give him the job.
