MADISON, Wis. (AP) – The leader of the Wisconsin Center for Investigative Journalism says he was blindsided by a budget provision that would specifically force the group to move its headquarters off the University of Wisconsin-Madison campus.   The center operates out of two offices in the university’s journalism school. UW-Madison pays for utilities and Internet access in exchange for the center hiring its students as paid interns and providing academic and journalism support.   But the Republican-controlled Joint Finance Committee voted Wednesday to end the arrangement.  The center is run by former Wisconsin State Journal reporter Andy Hall. He says he doesn’t know what precipitated the lawmakers’ sudden move, and he hopes they reconsider it.  The budget amendment was co-sponsored by two Republicans: state Sen. Alberta Darling and state Representative John Nygren. Neither immediately returned a message Wednesday.
