MADISON, Wis. (AP) — One of Wisconsin's largest real estate developers took his interest in buying several public buildings straight to the top, writing to Gov. Scott Walker. Records obtained by The Associated Press show developer Terrence Wall last month told Walker he was interested in buying several prominent state office buildings in Madison. Wall wrote to Walker about the same time the state was considering a change proposed by the governor that would allow state property to be sold without bids. It passed as part of the state budget over Democrats' objections that it would open the door to political cronies cutting special deals. Walker's spokesman, Tom Evenson, says to his knowledge no one replied to Wall's letter.
