Sign-On Letter to Senate Opposing S. 1814, the “Stop Sanctuary Cities Act" (August 4, 2015)

On behalf of the 139 undersigned national, state, and local organizations, we write to express our strong opposition to the “Stop Sanctuary Cities Act” (S. 1814), introduced by Senators Vitter, Flake, and McCain. If enacted into law, S. 1814 would mandate that all state and local law enforcement agencies (“LEAs’”) comply with all Homeland Security (“DHS”) immigration detainer requests, regardless of the constitutionality or validity of the detainers. At the same time S. 1814 would do nothing to solve the constitutional defects with DHS detainer requests that have led multiple federal courts to hold localities financially liable for violating the Constitution when they detain individuals on that basis. As a result, S. 1814 forces local LEAs into a Catch-22 position: either violate the Constitution and incur liability for unlawfully detaining individuals, or lose federal funding for following the Constitution and honoring community trust.
