My intended focus is on the widespread response—in cities, churches, campuses, and corporations that together comprise “sanctuary networks”¹—to the Trump Administration’s Executive Order 13768 Enhancing Public Safety in the Interior of the United States² as an instance of the changing relationship between federal, local, and private organizations in the regulation of immigration. After briefly covering the legal background of the Trump Interior E.O., the focus of the Article shifts to the institutional dynamics arising in communities. These institutional dynamics exemplify the beginnings of a reimagined immigration enforcement policy with a more integrative flavor.
