UW-Madison has no clear policy governing the presence of alcohol at university events off campus, an omission revealed Tuesday night with the release of a report that found a former senior UW athletic official had supplied alcohol to students ? some under the legal drinking age of 21 ? at a Rose Bowl party. The report released Tuesday night said John Chadima, former senior associate athletic director, resigned this month after a student employee accused him of sexual assault after an alcohol-fueled party in Chadima?s hotel room.
