DHS Threatens to Halt International Flights in Sanctuary Cities
The Trump Administration is developing plans to halt international flight processing at airports located in sanctuary cities, according to Homeland Security Secretary Markwayne Mullin. Speaking on Fox News in May 2026, Mullin stated the Administration is "currently drawing up plans" for the effort, framing it as retaliation against cities where local officials restrict cooperation with federal immigration enforcement. Mullin claimed that sanctuary cities cannot simultaneously refuse to enforce immigration laws while expecting the federal government to process international flights at their airports.
Mullin's threat targets major transportation hubs across the country. Airports potentially affected include New York's JFK, Los Angeles International, Newark Liberty, Chicago O'Hare, and San Francisco International, all among the busiest U.S. gateways for international travel. The Justice Department previously released a list identifying sanctuary cities, counties, and states as having policies restricting federal immigration enforcement cooperation. Mullin has previously suggested reducing Customs and Border Protection staffing at airports in these jurisdictions and met with airline and travel industry executives to discuss implementing such cuts.
The plan would inflict severe economic damage on communities across the country, regardless of political affiliation. According to Juliette Kayyam, a former DHS official under President Barack Obama, international flights cannot be diverted to alternative airports and would instead be cancelled entirely, disrupting both Democratic and Republican voters and causing substantial airline losses. Aaron Reichlin-Melnick, senior fellow at the American Immigration Council, characterized the proposal as "actively insane," warning that mass flight cancellations would generate economic chaos far beyond the targeted cities.
This threat represents the latest attempt by Trump to punish Democratic-led jurisdictions for disagreeing with his immigration agenda. The effort parallels earlier announcements to withhold federal funding from sanctuary states and cities, reflecting a broader pattern of weaponizing federal resources against political opponents. On his first day in office, Trump signed an Executive Order directing the Attorney General and Homeland Security Secretary to ensure sanctuary cities lose access to federal funds, establishing the framework for escalating punitive measures.
The proposal demonstrates Trump's willingness to weaponize federal authority against cities and states that oppose his policies, causing collateral damage to millions of citizens and the economy itself. By threatening to disrupt critical infrastructure serving both supporters and opponents alike, the Administration is deploying federal power as a tool of political retaliation rather than governance, undermining the principle that federal benefits and services should serve all Americans regardless of their city's immigration policies.
