Senator Cory Booker (D-NJ) proposed a bill earlier this month to rescind the authority of the Federal Government to enter into agreements with state and local law enforcement for the purposes of enforcing immigration law.
Senate Bill 303, entitled the, "PROTECT Immigration Act," would "discontinue a Federal program that authorizes State and local law enforcement officers to investigate, apprehend, and detain aliens in accordance with a written agreement with the Director of U.S. Immigration and Customs Enforcement and to clarify that immigration enforcement is solely a function of the Federal Government."
An accompanying bill has also been introduced in the House of Representatives.
The PROTECT Immigration Act would amend Section 287(g) of the Immigration and Nationality Act, preventing the Federal Government from entering into agreements with state and local law enforcement agencies to provide training in immigration enforcement.
Currently, the 287(g) program "allows a state and local law enforcement entity to enter into a partnership with ICE, under a joint Memorandum of Agreement" that provides the participating agency with training and "receives delegated authority for immigration enforcement within their jurisdictions."
