Sec. 8. Federal-State Agreements. It is the policy of the executive branch to empower State and local law enforcement agencies across the country to perform the functions of an immigration officer in the interior of the United States to the maximum extent permitted by law.

(a) In furtherance of this policy, the Secretary shall immediately take appropriate action to engage with the Governors of the States, as well as local officials, for the purpose of preparing to enter into agreements under section 287(g) of the INA (8 U.S.C. 1357(g)).

(b) To the extent permitted by law and with the consent of State or local officials, as appropriate, the Secretary shall take appropriate action, through agreements under section 287(g) of the INA, or otherwise, to authorize State and local law enforcement officials, as the Secretary determines are qualified and appropriate, to perform the functions of immigration officers in relation to the investigation, apprehension, or detention of aliens in the United States under the direction and the supervision of the Secretary. Such authorization shall be in addition to, rather than in place of, Federal performance of these duties.

(c) To the extent permitted by law, the Secretary may structure each agreement under section 287(g) of the INA in a manner that provides the most effective model for enforcing Federal immigration laws for that jurisdiction.

Sec. 9. Sanctuary Jurisdictions. It is the policy of the executive branch to ensure, to the fullest extent of the law, that a State, or a political subdivision of a State, shall comply with 8 U.S.C. 1373.

(a) In furtherance of this policy, the Attorney General and the Secretary, in their discretion and to the extent consistent with law, shall ensure that jurisdictions that willfully refuse to comply with 8 U.S.C. 1373 (sanctuary jurisdictions) are not eligible to receive Federal grants, except as deemed necessary for law enforcement purposes by the Attorney General or the Secretary. The Secretary has the authority to designate, in his discretion and to the extent consistent with law, a jurisdiction as a sanctuary jurisdiction. The Attorney General shall take appropriate enforcement action against any entity that violates 8 U.S.C. 1373, or which has in effect a statute, policy, or practice that prevents or hinders the enforcement of Federal law.

President Trump’s executive order seeking to halt federal funding to sanctuary cities contends that the main function of such jurisdictions is to protect “criminal aliens” from deportation, and warns ominously of a “public safety threat.” The order also would have us believe that public safety would be enhanced if we expanded efforts to remove undocumented immigrants by enlisting local police in a mass deportation campaign.

Quite the opposite is true. Sanctuary jurisdictions — 39 cities and 364 counties across the country have policies that limit local law enforcement’s involvement in enforcing federal immigration laws — increase public safety.

Trump’s executive order effectively revives two highly controversial programs that aimed to enlist state and local police and sheriffs in immigration enforcement: the 287(g) program and Secure Communities. The 287(g) program deputized local and state police and sheriffs to serve as immigration agents and was phased out in the latter years of the Obama administration because of excessive costs and administrative inefficiency. Secure Communities required that people arrested and processed in county jails be screened for immigration violations, and it, too, was phased out during the Obama administration, as mounting evidence showed that the program encouraged racial profiling by local law enforcement.
