Strange; I thought the city council made rules; not the mayor.
From WIKI...
The mayor is the leader in most United States municipalities (such as cities, townships, etc.). In the United States, there are several distinct types of mayors, depending on the system of local government. Under council-manager government, the mayor is a first among equals on the city council, which acts as a legislative body while executive functions are performed by the appointed manager. The mayor may chair the city council, but lacks any special legislative powers. The mayor and city council serve part-time, with day-to-day administration in the hands of a professional city manager. The system is most common among medium sized cities from around 25,000 to several hundred thousand, usually rural and suburban municipalities.
In the second form, known as mayor-council government, the mayoralty and city council are separate offices. Under a strong mayor system, the mayor acts as an elected executive with the city council exercising legislative powers. He or she may select a chief administrative officer to oversee the different departments. This is the system used in most of the United States' large cities, primarily because mayors serve full-time and have a wide range of services that they oversee. In a weak mayor or ceremonial mayor system, the mayor has appointing power for department heads but is subject to checks by the city council, sharing both executive and legislative duties with the council.
Well, maybe that is a fact. Only problem is have is I heard what I heard come right out his mouth.
