POLITICS, CHICAGO STYLE: Crain’s investigation: The high price of political payback at McCormick Place. “Illinois House Speaker Michael Madigan cost taxpayers nearly half-a-billion dollars by blocking repeated efforts to restructure McCormick Place bonds and finance a much-needed second hotel at the convention center, a Crain’s investigation finds. . . . By holding up refinancing, the speaker also denied McCormick Place the money to build a new hotel. That bought time for clout-heavy developers Gerald Fogelson and Cleveland-based Forest City Enterprises Inc. to push a controversial land swap and hotel deal with McCormick Place on property just north of the convention center. Both were then clients of Mr. Madigan’s law firm, Madigan & Getzendanner, but the speaker denies any connection.”
