HR-5604-119
Referred to the House Committee on Armed Services.
Sponsored by Andrea Salinas (D-OR)
What it does
This bill would prohibit members of the U.S. Armed Forces and the National Guard from being ordered to enforce immigration laws. It would codify this restriction in alignment with the Posse Comitatus Act, which generally bars the military from performing domestic civil law enforcement functions.
Who benefits
Unauthorized immigrants who might otherwise be subject to military-conducted enforcement actions. Civil liberties organizations and communities concerned about militarized domestic policing. State governors who would retain clearer authority over National Guard deployments within their states. Legal residents and citizens in border regions who may have concerns about military presence in civilian law enforcement contexts. Military service members who would be shielded from orders to perform immigration enforcement duties outside their traditional role.
Who is hurt
Federal agencies — particularly DHS and CBP — that have used or sought to use National Guard personnel to support immigration enforcement operations at the border. Administrations that favor deploying military or Guard assets to supplement civilian immigration enforcement. Border communities and local governments that support a larger military role in deterring unauthorized border crossings. Taxpayers who fund parallel civilian enforcement agencies if military support is removed and additional civilian capacity must be funded instead.
Supporters argue
Supporters argue that using the military for immigration enforcement blurs the constitutional line between military and civilian authority that the Posse Comitatus Act was designed to protect. They contend that immigration enforcement is a civil legal function — not a military one — and that deploying armed service members in that role risks civil liberties violations, as military personnel are trained for combat rather than civilian due process standards. They point to documented incidents of National Guard units conducting stops and detentions of civilians near the border as evidence that the line has already been crossed without adequate legal guardrails.
Opponents argue
Opponents argue that the southern border faces an operational security challenge that civilian agencies alone cannot adequately address, and that targeted military support — including National Guard deployments authorized by state governors — has historically supplemented, not replaced, civilian enforcement. They contend the bill would strip commanders and governors of flexible tools already used under Operations Jumpstart and Phalanx, which were structured to keep Guard members in a support role without direct law enforcement authority. They further argue the bill conflates support functions like surveillance and logistics with actual law enforcement, potentially banning activities that do not implicate Posse Comitatus concerns.
Constitutional context
The Posse Comitatus Act (18 U.S.C. § 1385) restricts use of the Army and Air Force for domestic law enforcement; this bill would extend that principle explicitly to immigration enforcement. Under Youngstown Sheet & Tube v. Sawyer (1952), Congress has broad authority to define and limit the scope of military deployments, and presidential military authority is at its lowest when Congress has restricted it. The Commander-in-Chief Clause (Art. II, §2) grants the President operational command, but the Military Powers Clauses (Art. I, §8, cls. 12-14) give Congress authority to make rules governing the armed forces.
Checks and balances
Congress would gain explicit statutory authority to limit how the Executive deploys military and National Guard personnel domestically; the President's Commander-in-Chief authority would be constrained by this legislative restriction, consistent with Youngstown Zone 3 analysis where presidential power is at its lowest ebb.
Historical precedent
The Posse Comitatus Act of 1878 established the foundational prohibition on military domestic law enforcement; National Guard border deployments under Operations Jumpstart (2006) and Phalanx (2010) were structured specifically to avoid direct law enforcement contact, reflecting ongoing tension over where the legal line falls.
