University of Colorado professor Ward Churchill has two weeks to respond to a report that says he repeatedly fabricated his research and plagiarized others' work.
An investigation of Churchill began after he wrote an essay that likened some World Trade Center victims to a Nazi who helped orchestrate the Holocaust.
CU found they could not fire Churchill for the comments, but would look into other allegations.
The report from a five-member investigative panel was released yesterday.
It says among other things that Churchill fabricated evidence about how American Indians were exposed to smallpox and plagiarized a Canadian environmental group's pamphlet about dams.
Four members say Churchill should be suspended without pay and one said he should be fired.
University officials say they expect to decide his fate by June eighth.
Churchill is calling the report transparently ridiculous and laughable.
The committee also raised concerns about the timing and motives for the university's decision to launch the investigation.
School officials defended their decision, saying the research allegations couldn't be ignored.
