Well, it's true

From the Wikipedia entry on former Illinois governor Otto Kerner, Jr.:

In 1969, Marge Lindheimer Everett, manager of Arlington Park and Washington Park race tracks admitted bribing then Governor Otto Kerner and his Finance Director, Ted Isaacs, to gain choice racing dates and to get two expressway exits for her Arlington Park racetrack. The bribes were in the form of stock. Amazingly, the scandal came to light because Everett had deducted the value of the stock on her federal income tax returns under her own theory that bribery was an ordinary and necessary business expense in Illinois.
