MADISON, Wis. (AP) – The University of Wisconsin System would miss out on a $181 million spending increase in the upcoming budget, and also lose an additional $2.5 million under a bill before the Legislature’s budget-writing committee.  Governor Scott Walker initially proposed the $181 million increase. But he revised that figure this month following news the university has a $650 million surplus. He called for a two-year tuition freeze and additional spending cuts.   The Joint Finance Committee on Thursday debated a bill that would remove even more funding. It would also maintain the tuition freeze and impose reporting requirements on the UW System Board of Regents.  The bill represents Republicans’ outrage at UW System officials after learning the system amassed the surplus even while raising tuition for six straight years.
