DHS Plans International Travel Shutdown At Airports In Democratic-Led Cities—But Not Newark

Homeland Security Secretary Markwayne Mullin announced plans to remove customs officers from international airports serving Democratic-led sanctuary cities, a move that has generated widespread criticism from industry groups and political figures.

Mullin stated that the plan is part of a broader effort to enforce federal immigration laws in sanctuary cities, which he claims hinder DHS operations. The plan involves pulling Customs and Border Protection (CBP) officers from airports like Newark, Los Angeles, and others in jurisdictions identified as sanctuary cities.

However, the White House has not endorsed the plan, and DHS confirmed to Forbes that it is still in the planning stage. The move follows recent protests at Delaney Hall, a detention facility in New Jersey, which Mullin linked to the potential withdrawal of customs officers at Newark Airport. Local officials, including New Jersey Governor Mikie Sherrill, condemned the plan, citing economic and security concerns.

Potential Impact on International Travel and Economy

This plan, if enacted, could disrupt international travel, harm the U.S. economy, and damage the country’s reputation for reliable aviation operations. Experts warn that removing customs officers could lead to delays, increased security risks, and significant economic losses, especially in cities with high international visitor traffic. The move also raises concerns about the politicization of immigration enforcement and its broader implications for U.S. diplomacy and domestic stability.

Background of Sanctuary Cities and DHS Enforcement Policies

Since an April 2025 executive order by President Donald Trump, the Department of Justice has identified 18 jurisdictions as sanctuary cities, citing their policies that impede federal immigration enforcement. These cities include New York, Los Angeles, Chicago, and Newark, among others. The Biden administration has maintained a stance that emphasizes local enforcement and immigration reform, contrasting with Mullin’s approach.

Recent protests at Delaney Hall, a detention facility operated by a private contractor for ICE, have intensified tensions between federal authorities and local officials. Mullin’s threat to withdraw customs services is seen as part of a broader political effort to pressure sanctuary jurisdictions over immigration policies.

“Instead of ensuring people who want to exercise their constitutional rights have the ability to do so, we have threats to shut down the international terminal in Newark right before the FIFA World Cup.”

“We are currently drawing up plans for these sanctuary cities where local policies hinder federal enforcement, and we believe we shouldn’t process international flights into their cities either.”

Unclear Status and Next Steps for the Plan

It remains unclear whether the DHS will proceed with the plan to withdraw customs officers, as it has not received White House approval. The timeline for any implementation is also uncertain, and legal or diplomatic challenges could alter or halt the initiative.

Next Developments and Official Responses Expected

The Biden administration is likely to clarify its position in the coming weeks, possibly opposing or modifying Mullin’s proposal. Congressional hearings and industry hearings may also scrutinize the plan, and local officials will continue to oppose any disruptions to airport operations. Monitoring DHS announcements and congressional responses will be key to understanding the plan’s future.
