Mahoney’s office and Madison police could not be reached for comment Thursday to say if the bill would affect any of their policies or operations.

Madison was among the cities that Assembly Speaker Robin Vos, R-Rochester, said last year was being targeted by the bill — though Madison officials disputed the term “sanctuary city” as accurately describing their policies. It typically is applied to cities or counties that refuse to cooperate with federal authorities to enforce immigration law.

Constitutional concerns cited

The Badger State Sheriffs’ Association, in written testimony to the committee, flagged the provision requiring compliance with ICE detainers. If doing so requires the person to be detained past what is allowed under the charge or charges for which they initially were detained, it cannot be done “without violating the person’s constitutional rights,” the association wrote. National sheriffs’ groups are working with federal authorities to resolve this issue, the association wrote.

Darryl Morin, a spokesman for the Wisconsin chapter of the League of United Latin American Citizens, or LULAC, said the bill would “send a message of fear and division and have a chilling effect on police-community relations.”
