Why It Matters
Idaho is at the center of a legislative debate over immigration enforcement as House lawmakers moved to require all local law enforcement agencies statewide to enter formal agreements with federal immigration authorities. The procedural maneuver affects how county sheriffs and municipal police departments would interact with federal immigration enforcement operations going forward.
The amendment, if it becomes law, would obligate local agencies to participate in the federal 287(g) program — a significant shift in how Idaho communities with limited law enforcement resources manage immigration-related responsibilities.
What Happened
During an evening floor session on April 1, Idaho House Representatives Jordan Redman (R-Coeur d’Alene) and Dale Hawkins (R-Fernwood) introduced an amendment that entirely replaced the language of an existing bill. The procedure, informally known as “radiator capping,” strips the content from a bill while preserving its legislative vehicle.
The bill in question, Senate Bill 1247, was originally written to require state and local governments — along with large government contractors — to use the federal E-Verify work authorization program to confirm employees are legally authorized to work in the United States.
Redman and Hawkins removed all of SB 1247’s existing language and replaced it with the contents of House Bill 659, which would mandate that local law enforcement agencies across Idaho enter into 287(g) agreements with federal immigration authorities. Under such agreements, local officers are deputized to perform certain immigration enforcement functions typically handled by U.S. Immigration and Customs Enforcement (ICE).
The sponsors indicated the move came after negotiations on the original immigration enforcement measure stalled. Rather than allow the session to close without action, lawmakers chose the late-session takeover strategy to advance the policy through a different legislative path. This development follows the Idaho Senate Committee’s earlier advancement of a bill also requiring local law enforcement to enter federal immigration enforcement agreements, signaling consistent legislative pressure on this issue from both chambers.
By the Numbers
287(g) Program: As of early 2026, approximately 150 law enforcement agencies nationally participate in the 287(g) program across more than 30 states, according to ICE data.
Idaho counties: Idaho has 44 counties, each with a sheriff’s office that would be subject to mandatory participation requirements under the rewritten bill.
E-Verify: The original SB 1247 would have applied E-Verify requirements to state agencies and contractors with workforces of significant size — a mandate that has been adopted in roughly 22 states in various forms.
Session timing: The amendment was introduced on April 1, indicating the maneuver occurred in the final stretch of Idaho’s 2026 legislative session, leaving limited time for deliberation or opposition to organize.
Legislative timeline: The bill must still clear additional procedural steps before it could reach Governor Brad Little’s desk for consideration.
Zoom Out
The push to mandate 287(g) agreements at the state legislative level reflects a broader national trend in which states are moving to institutionalize cooperation between local law enforcement and federal immigration agencies. Several states, including Texas and Florida, have enacted legislation in recent years requiring or incentivizing local participation in federal immigration enforcement programs.
The procedural “radiator capping” tactic itself is not unique to Idaho — it has been used in multiple state legislatures to revive or redirect stalled policy priorities late in a session when sponsor coalitions have enough votes to pass new content but lack the time to advance a fresh bill through committee. Idaho lawmakers have also been active on related government accountability measures, as seen in the recent procurement reform bill sent to the governor ahead of a major Medicaid contract decision.
At the federal level, the Trump administration has emphasized expanding 287(g) partnerships as part of its immigration enforcement strategy, creating political alignment between state-level Republican majorities and federal executive priorities.
What’s Next
The amended Senate Bill 1247 must return for further legislative action before it can advance to the governor. Lawmakers will need to reconcile the House amendment with the Senate’s original version, potentially requiring a conference committee or additional floor votes in both chambers.
Governor Brad Little has not publicly stated his position on mandatory 287(g) agreements. If signed into law, implementation would require coordination between the Idaho Office of the Attorney General, the Idaho Sheriffs’ Association, and ICE to establish the formal agreements with local agencies statewide.
Opponents of the mandate, including some law enforcement officials, have previously raised concerns about resource strain and jurisdictional complications that can arise from mandatory federal partnership requirements.
