University of Wisconsin System President Ray Cross says the chancellor at U-W-La Crosse exercised poor judgment when he paid a porn actress to speak on campus. Chancellor Joe Gow has apologized for the November 1st appearance of Nina Hartley. She was paid five-thousand dollars of out Gow’s discretionary fund. Cross says he’s ordering an audit of that discretionary fund due to the questionable decision. Gow has said he invited Hartley to campus to promote the U-W System’s freedom of expression policy.
