Bill Information: H0659 – Mandatory 287(g) Immigration Enforcement Participation

Session: 2026 Regular Session
Status: Dead
Last Action: Senate State Affairs Committee (08:00:00 3/16/2026 Room WW55) (Mar 16, 2026)

Bill Summary

House Bill 659 creates new Section 19-626 in Idaho Code, mandating that every law enforcement agency in the state—including all municipal police departments and county sheriff’s departments—apply for and participate in federal Section 287(g) programs with Immigration and Customs Enforcement (ICE). Section 287(g) of the Immigration and Nationality Act allows specially trained local peace officers to perform immigration enforcement functions including investigation, apprehension, and detention of noncitizens under federal oversight.

The bill requires agencies to participate in any available 287(g) program model, specifically mentioning the jail enforcement model and warrant service officer model operated by the Department of Homeland Security. If a law enforcement agency cannot enter into a 287(g) memorandum of agreement, it must publish a statement explaining why and describing any alternative cooperation efforts with ICE’s enforcement and removal operations. The bill includes an emergency clause making it effective July 1, 2026.

Overall Assessment

This bill transforms every local law enforcement agency in Idaho into an extension of federal immigration enforcement by requiring participation in 287(g) programs. Local police and sheriff’s deputies will gain authority to investigate, apprehend, and detain individuals based on immigration status during their regular duties. The mandate applies statewide regardless of local community preferences or resource constraints, fundamentally changing the relationship between local law enforcement and immigrant communities.
