In a surprise move, a bill to greatly expand gambling in Illinois is on Gov. Pat Quinn’s desk.

Illinois Senate President John Cullerton had used a parliamentary move to hold the bill, although it had passed both the House and the Senate in 2011. Cullerton released the bill Tuesday, sending it to the governor.

The measure calls for the creation of several new casinos in Illinois and adding slot machines at race tracks and at O’Hare and Midway airports.

A spokeswoman for the governor’s office had no immediate comment on the move, but the governor has criticized other gambling expansion efforts for not having strict enough ethics controls and for expanding gambling too much.
