The Obama administration is starting to shut down a program that deputized local police officers to act as immigration agents. Immigration and Customs Enforcement officials have trained local officers around the country to act as their agencies’ immigration officers. Working either in jails or in the field, the officers can check the immigration status of suspects and place immigration holds on them. The program, known as 287(g), reached its peak under President George W. Bush, when 60 local agencies signed contracts with ICE to implement it. But that trend slowed significantly under President Obama— only eight agencies have signed up since he took office, and none has done so since August 2010.
