The University of Colorado professor under fire for calling victims of the 9-11 attacks “Little Eichmans,” reportedly trained a domestic terror group.

Ward Churchill taught the revolutionary group the Weathermen how to make bombs and fire weapons, according to a Fox News report citing the Jan. 18, 1987 issue of the Denver Post.

The revelation is among many reported since Churchill prompted a national furor with publicity of an essay he wrote titled “Some People Push Back: On the Justice of Roosting Chickens.”

Written shortly after the Sept. 11 attacks, it describes the thousands of American victims who died in the World Trade Center inferno as “little Eichmanns” — a reference to notorious Nazi war criminal Adolf Eichmann — who were perpetuating America’s “mighty engine of profit.” They were destroyed, he added, thanks to the “gallant sacrifices” of “combat teams” that successfully targeted the World Trade Center towers and the Pentagon.

Churchill resigned his position as head of the Colorado University ethnic studies program but kept his $96,000 per year teaching post. He has steadfastly refused to apologize for his comments.

Meanwhile, the University of Wisconsin-Whitewater said it will allow Churchill to speak next month, a decision that sparked outrage among state lawmakers, the Associated Press reported.

Chancellor Jack Miller said in a statement he finds the professor’s views repugnant but believes it’s necessary to permit him to speak under First Amendment principles.

A former student of Churchill’s says she heard him justify the 1995 Oklahoma City bombing during a class lecture.

Kimberly Hickel said the professor “actually stood in front of our class and said how the FBI got what they deserved. It was awful.”

In an interview last April with the left-leaning Brooklyn-based magazine Satya, Churchill was quoted saying the United States should “cease to exist” and that “more 9-11s may be necessary.”
