He was criticized  for referring to the victims of the 9/11 attacks as "little Eichmanns", comparing them to the infamous Nazi leader, in an article titled Some People Push Back: On the Justice of Roosting Chickens  that was published shortly after 9/11.
In 2006, the university's Standing Committee on Research Misconduct found Churchill guilty of several charges, including plagiarism and fabrication of information.
Churchill was fired by the University of Colorado on July 24, 2007.  Churchill then filed a lawsuit, claiming the university violated his right to free speech.  In a Fox News interview with University of Colorado President Hank Brown, Mr. Brown defended Ward Churchill's firing.  Bill O'Reilly says "the freedom of speech issue is bogus. It's all about performance. If a ball player can't catch the ball, he's fired. If a teacher can't reason, he should be fired as well." 
Churchill in 2009 won his lawsuit against the University and was awarded $1, but the judge refused to order his reinstatement as a professor. Churchill remains unrepentant, unscholarly and unemployed.
