MADISON, Wis. (AP) — The co-chairmen of the state Legislature’s Joint Finance Committee are pressing the Milwaukee Bucks owners to be specific about how much a new arena would cost. Assembly Speaker Robin Vos and Rep. John Nygren met separately with Milwaukee Mayor Tom Barrett in Madison this week and agreed that in order for the project to move forward legislators and elected officials need to know exactly what the Bucks have in mind. Gov. Scott Walker has proposed selling $220 million in state bonds to help pay for the arena. Legislators have been pressing Barrett and Milwaukee County Executive Chris Abele to say how much the city and county is willing to contribute. Both Vos and Nygren agree the sentiment among legislators is that $220 million in state bonds is too high.
