University of Minnesota Vice President Karen Himle, who pulled the plug on a documentary that was to run on Twin Cities Public Television in October, is being asked to resign by a sustainable agriculture advocacy organization, according to the local Star-Tribune. Himle canceled the broadcast of “Troubled Waters: A Mississippi River Story,” which was produced by the university. The paper reported that Himle is married to John Himle, c.e.o. of Himle Horner Inc., a PR firm that represents the Minnesota Agri-Growth Council, an agribusiness advocacy association; he denied any role in the cancellation. The Land Stewardship Project is calling for her to step down. Himle has not spoken to the press but said through a university spokesperson that she made the decision after hearing concerns from faculty members about the science behind the film, which deals in part with agricultural pollution. University President Robert Bruininks issued a statement supporting Himle.
