Trump’s newly appointed DHS Secretary is threatening to shut down international travel at major airports in sanctuary cities that refuse to cooperate with federal immigration enforcement, escalating a high-stakes standoff between Washington and blue-state strongholds.
Story Snapshot
- DHS Secretary Markwayne Mullin proposes withdrawing customs officers from airports in sanctuary cities, potentially halting international flights at JFK, LAX, O’Hare, and other major hubs
- The move targets cities refusing to cooperate with ICE amid a congressional deadlock over DHS funding, affecting over 50 million annual travelers at New York airports alone
- California Governor Gavin Newsom’s office calls the plan a “stupid idea” that would devastate regional economies
- The proposal comes just weeks before the FIFA World Cup in June 2026, raising stakes for international travel and commerce
Federal Leverage Against Sanctuary Resistance
DHS Secretary Markwayne Mullin announced on April 7, 2026, that the department is considering withdrawing Customs and Border Protection officers from international airports in sanctuary cities that refuse to assist with federal immigration enforcement. The proposal would effectively halt international arrivals and departures at major travel hubs including New York’s JFK and LaGuardia, Los Angeles International, Chicago’s O’Hare, San Francisco International, Seattle-Tacoma, Newark, Boston, Philadelphia, Denver, and New Orleans. Mullin stated during interviews with reporters and Fox News host Bret Baier that “if cities say they’re not going to enforce immigration policies, it doesn’t make sense to process international travelers” at those locations.
Targeting Blue Cities Amid Budget Impasse
The Trump administration’s proposal directly targets Democratic-led cities included on a Department of Justice list of 32-plus sanctuary jurisdictions published in October 2025. These cities have maintained policies limiting local law enforcement cooperation with Immigration and Customs Enforcement, dating back to protections established in the 1980s. The customs withdrawal threat emerges amid a partisan congressional standoff over DHS funding that began in mid-February 2026, with Democrats opposing Trump’s immigration enforcement budget increases without broader reforms. This tactic represents a departure from prior Trump-era attempts to defund sanctuary cities through executive action, which courts repeatedly blocked during his first term.
Economic Fallout and Political Calculations
The potential shutdown of customs operations at these airports would deliver severe economic consequences to affected regions. New York’s airports alone process more than 50 million international arrivals annually, supporting billions in tourism revenue and international commerce. Airlines, businesses, and travelers would face immediate disruptions, with international flights potentially rerouted to airports in jurisdictions cooperating with federal immigration authorities. California Governor Gavin Newsom’s office responded on social media, warning “if you thought the economy was bad, just wait” and labeling the proposal a “stupid idea.” The timing amplifies pressure, coming just weeks before the FIFA World Cup scheduled for June 2026, when international travel volumes typically surge.
Federal Authority Versus Local Autonomy
Mullin frames the proposal as enforcing federal supremacy over immigration law, arguing sanctuary policies illegally contradict federal authority. The administration maintains that cities refusing cooperation forfeit the right to federally-provided customs services essential for international travel. Critics counter that the plan amounts to economic blackmail, punishing millions of residents and visitors for local policy disagreements. Legal experts predict court challenges similar to those that blocked Trump’s first-term sanctuary city funding cuts, though the administration may argue customs deployment falls within executive discretion. The standoff reflects broader frustrations among Americans across the political spectrum who increasingly view Washington as weaponizing federal power rather than solving fundamental immigration challenges through honest negotiation.
Implementation Uncertain as Pressure Mounts
As of April 8, 2026, Mullin described the customs withdrawal as “an option” under discussion with President Trump rather than a finalized decision. The secretary indicated ongoing conversations about alternatives including budget reconciliation to secure ICE and CBP funding without Democratic support in Congress. No implementation timeline has been announced, leaving airports, airlines, and city officials uncertain whether the threat represents serious policy or negotiating leverage. The proposal nonetheless signals the administration’s willingness to use federal control over critical infrastructure as a cudgel against jurisdictions it views as obstructing lawful immigration enforcement, raising questions about whether elected officials prioritize political battles over the economic wellbeing of the communities they claim to serve.
