Sanctuary cities are back in the news, thanks to Immigration and Customs Enforcement raids. The raids come only weeks after President Trump signed an executive order requiring that federal funds be withheld from sanctuary cities.
This order is a betrayal of the federalism that conservatives claim to support.
Even if the sanctuary provisions of the order did not raise serious constitutional concerns, they would be unwise policy. According to the Center for Immigration Studies, which supports limiting immigration, there are about 300 jurisdictions that deserve the sanctuary label, which describes areas where local officials have decided not to assist the federal government in enforcing immigration law.

Sanctuary policies and practices include barring police from asking crime victims or witnesses about immigration status, as well as forbidding officers from stopping someone solely to determine their status.
