CBP Pullout THREAT Shakes Major Airports

A single federal staffing decision could reroute international travel away from “sanctuary” airports—and force blue-city leaders to choose between local politics and federal immigration enforcement.

Quick Take

DHS Secretary Markwayne Mullin says he is considering pulling CBP (U.S. Customs and Border Protection) airport operations from sanctuary jurisdictions that refuse to cooperate with ICE.
Without CBP processing for international arrivals, affected airports could lose direct international flights and see passengers rerouted to other cities.
No formal DHS action or target list has been announced; the idea remains under review after Mullin’s April 6 Fox News interview.
The threat escalates the long-running federal-versus-local fight over sanctuary laws and could trigger legal challenges if implemented.

Mullin’s leverage point: CBP staffing at international terminals

DHS Secretary Markwayne Mullin, confirmed after President Trump fired former Secretary Kristi Noem in late March 2026, floated a major escalation in the sanctuary-city showdown during an April 6 interview with Fox News host Bret Baier. Mullin said DHS is taking a “hard look” at whether international airports in sanctuary jurisdictions should keep CBP support if local officials won’t cooperate with ICE. The immediate practical effect would be aviation disruption, not just paperwork.

International air travel depends on federal inspection capacity: CBP officers process passports, visas, and customs declarations for arriving passengers. If an airport loses that federal footprint, it cannot lawfully process most international arrivals at scale, meaning airlines would have to shift routes, add connection points, or drop service. Reports describe the concept as redirecting flights into jurisdictions that “want to work” with federal enforcement, effectively making airport access a lever to push policy compliance.

Why sanctuary jurisdictions are the target in this round

Sanctuary policies, which expanded from earlier local protections into formal limits on cooperation with federal immigration enforcement, are the center of this conflict. As of August 2025, the federal government recognized a set of sanctuary jurisdictions that included 12 states plus Washington, D.C., along with counties and cities. The current dispute focuses on whether local rules that restrict communication, detention, interviews, or assistance in civil immigration enforcement make it harder for ICE to act after travelers clear an airport.

Washington state provides a detailed example of the specific provisions being criticized. Reporting describes state law as restricting local aid in federal civil immigration enforcement, limiting detentions based solely on immigration status, constraining data sharing, and narrowing when local authorities can cooperate with federal detainers or interviews. Those limits may be popular with progressive voters, but they also create a predictable friction point: ICE can have federal authority, yet still depend on local systems and cooperation to execute certain actions efficiently.

What’s new: an operational threat, not just funding pressure

Previous fights often centered on federal grants, executive actions, and attempts to condition funding—moves that repeatedly ran into court challenges during earlier Trump-era disputes. Mullin’s comments signal a different approach: the threat is not only financial, but operational. By tying CBP deployment to cooperation levels, DHS would be using the federal government’s control of border inspection staffing to reshape how—and where—international travel enters the country, especially at major hubs in blue states.

That distinction matters politically because it shifts the battlefield from city hall budgets to airline schedules and passenger convenience. The airports discussed across coverage include major international gateways such as those serving New York, Los Angeles, San Francisco, Chicago, Seattle, and Denver. If DHS actually reduced or removed CBP operations, the immediate pain would likely fall on travelers, local tourism, and business activity, while local officials and the White House would blame each other for the fallout.

Economic and legal questions remain unanswered

As of April 7, 2026, DHS has not announced a formal policy, a timeline, or a definitive list of airports, and CBP/DHS did not provide an official response to media inquiries described in the reporting. That leaves basic implementation questions open, including how quickly staffing could be shifted, whether partial reductions could occur short of a full pullout, and what alternative routing plans airlines would pursue if inspections were curtailed at a major hub.

The legal fight, if this moves from talk to action, is also likely to be central. Sanctuary jurisdictions have long argued they can limit cooperation based on local authority and priorities, while the federal government points to its supremacy in immigration enforcement. Even some critics of sanctuary policies may question whether punishing broad regional commerce is the cleanest tool for solving what is, at core, a law-enforcement coordination dispute. For now, the facts support only this: DHS is signaling a pressure campaign, and the next steps are not yet public.
