Mayor Rahm Emanuel, known for his temper and willingness to go toe-to-toe, reportedly lost it with Gov. Pat Quinn in a recent phone call.
A political source with knowledge of the situation who declined to be named told Ward Room Emanuel is upset Quinn wants stronger ethics rules when it comes to gaming.
Emanuel has said Chicago has a casino but it's in Hammond, which continues to rake in money the mayor believes belongs to the Windy City. Indiana has stronger ethics rules, though, including a ban on campaign contributions for anyone with a gaming interest to Indiana lawmakers.
Quinn calls for proposed legislation to be created with full integrity and ethics oversight. The governor remains skeptical of gambling expansion in Illinois and has declared his intention to veto a bill that would allow slots at racetracks and add five casinos, including one in Chicago.
Word has it Emanuel had some very unkind words for Quinn over the mayor's wish for a Chicago casino.
At last check, pension reform and gaming is on hold in Illinois.
Emanuel's office has not returned calls for comment.
