MADISON, Wis. (AP) – The head of the Center for Investigative Journalism in Wisconsin says he is grateful to Republican Governor Scott Walker for vetoing a provision in the state budget that would have kicked the center off the University of Wisconsin-Madison campus.     Republican lawmakers placed the provision in the state budget, but the Republican governor says he thinks the center’s relationship with the university is an issue for the UW System’s Board of Regents.  Andy Hall is the center’s executive director. He said Sunday the center is celebrating the governor’s veto at the same time it kicks off a fundraising drive to help pay for its work.  The center is a nonpartisan investigative news organization that offers its stories free to mainstream media outlets. It occupies two offices in the university’s journalism school.
