Emanuel wants the state to extend the life of a 2 percent hotel tax, which now brings in about $45 million a year, from its expiration at the end of 2032. Currently, the money from that tax is used to repay the loans used to pay for U.S. Cellular Field, the home of the White Sox. Emanuel wants to continue the tax until 2066 to help pay off a new 40-year bond issue and provide some cushion, said Lori Healey, CEO of the Metropolitan Pier and Exposition Authority.
