U.S. Department of Homeland Security Secretary Markwayne Mullin said he suggests reducing Customs and Border Protection staffing at airports located in sanctuary jurisdictions [1, 2].
The proposal marks a significant escalation in the federal government's effort to compel local governments to align with national immigration agendas. By targeting critical transportation hubs, the administration seeks to leverage economic and operational disruptions to force cooperation from cities that limit their interaction with federal immigration authorities [3, 6].
Reports indicate that Mullin first floated the idea during a Fox News appearance in early April 2026 [6]. The proposal surfaced in public reporting this week, sparking debate over the legality and practicality of such a move [2, 3].
There are contradictions regarding the severity of the proposed action. Some reports state the plan involves reducing staffing levels at these airports [1]. Other sources suggest a more drastic measure, including the possibility of halting customs processing entirely for international passengers, and cargo [2, 4, 5].
The targets of this potential policy are major U.S. airports that serve cities with sanctuary policies [2, 5]. These jurisdictions typically restrict local law enforcement from assisting federal agents in the enforcement of federal immigration law.
Transportation officials and airlines have expressed concern over the pitch [4]. A total halt or significant reduction in processing would likely create massive delays for travelers and disrupt global supply chains—potentially impacting thousands of flights and shipments daily.
Secretary Mullin said he will reiterate the threat to cut these services to pressure sanctuary jurisdictions to cooperate with federal immigration enforcement [2, 3].
“The administration seeks to leverage economic and operational disruptions to force cooperation from cities.”
This proposal represents a shift toward using critical infrastructure as a tool for political and legal leverage. If implemented, the move would create a conflict between federal security mandates and local sanctuary ordinances, likely resulting in immediate legal challenges and significant logistical disruptions at some of the busiest travel hubs in the country.
