Atlanta’s city jail will no longer accept immigrants detained by federal officials, the mayor announced Thursday, saying it was the best way to demonstrate her administration’s opposition to current “inhumane” national immigration policies.

Mayor Keisha Lance Bottoms signed an executive order directing the Atlanta City Detention Center to stop accepting detainees of the U.S. Immigration and Customs Enforcement. The jail had been receiving the detainees under an agreement with the U.S. Marshals Service.
