Mobilizing Against Sanctuary Cities Act This bill makes a state or local government ineligible for federal financial assistance for a minimum of one year if it restricts or prohibits an agency or official from (1) communicating with the responsible federal immigration agency information regarding an individual's citizenship or immigration status, or (2) maintaining or exchanging information about an individual's status. Such governmental entities are known as sanctuary cities or jurisdictions. The bill restores assistance eligibility upon a Department of Justice (DOJ) determination that the jurisdiction no longer restricts or prohibits such access. DOJ shall determine each year which state or local jurisdictions are not in compliance with immigration requirements and report such determination to Congress.
