Homeland Security’s Plan to Squeeze International Flights

Nick Miroff, The Atlantic, May 21, 2026

In early April, shortly after Markwayne Mullin took over the Department of Homeland Security, he floated an idea on Fox News that wasn’t taken seriously; it sounded, in fact, like a proposal from someone very new on the job: Mullin threatened to cut federal screening of international passengers and cargo at airports in cities with “sanctuary” policies, which limit cooperation with Immigration and Customs Enforcement. Such a move would trigger flight cancellations to airports in New York, Los Angeles, Chicago, and other major cities and force airlines to reroute to other destinations. Mullin’s proposal seemed more like a wild swing than a real plan.

The new secretary is pushing forward anyway. Last Wednesday, Mullin convened a small group of airline and travel-industry executives at DHS headquarters in Washington and told them he may reduce Customs and Border Protection staffing at major airports that serve sanctuary jurisdictions. Mullin told the executives the locations could include Portland International Airport, in Oregon; New York City–area airports such as John F. Kennedy International Airport and Newark Liberty International Airport; and Washington Dulles International Airport, according to two people with knowledge of the discussion who were not authorized to speak publicly. Mullin did not indicate when DHS would begin the pullback, but it would likely occur sometime after the United States finishes hosting the World Cup in July, the two people told me.

Travel executives are alarmed, and have told DHS that international travelers and cargo cannot be easily routed elsewhere, these people said. The disruption would cause chaos in major U.S. airports and inflict significant economic damage beyond the cities Mullin is seeking to pressure, executives have told the department. “The message was this is a real proposal that is being considered by the administration,” one of the people with knowledge of the meeting told me, calling the potential impact on the airline industry “devastating.”

When Mullin first mentioned the idea during the interview on Fox News, he described it as a creative way to pressure the cities to comply with ICE. The Trump administration wants access to city and county jails so ICE officers can take custody of potential deportees before they are released. “If they’re a sanctuary city and they’re receiving international flights, and we’re asking them to partner with us at the airport, but once they walk out of the airport, they’re not going to enforce immigration policy—maybe we need to have a really hard look at that,” Mullin said. “I’m going to have to be forced to make hard decisions.”

Getting more cooperation from sanctuary cities, even on a limited basis, would amount to a political win for Mullin and Homan. Trump officials are suing many of these cities in federal court and have threatened to withhold federal grants, but Mullin’s airport proposal goes a step further, enlisting the travel industry in the pressure campaign.
