TL;DR
Homeland Security Secretary Mullin announced plans to eliminate customs screening at international airports in Democratic-led sanctuary cities. The move faces strong opposition from industry groups, local officials, and some members of Congress. The plan is still in development and has not been approved by the White House.
Homeland Security Secretary Markwayne Mullin has announced a plan to remove customs screening from international airports serving Democratic-led sanctuary cities, a move that has generated widespread backlash from industry groups, local officials, and members of Congress.
Mullin stated that the plan is part of a broader effort to enforce federal immigration laws more strictly in sanctuary cities, which he claims impede immigration enforcement. The DHS confirmed that the agency is currently drafting plans to implement these removals, although the White House has not approved the initiative.
The move follows Mullin’s threats to withdraw Customs and Border Protection officers from Newark International Airport after protests at the nearby Delaney Hall ICE detention center. The plan would extend to other airports in sanctuary cities, which are designated by the Department of Justice for policies that allegedly obstruct federal immigration enforcement.
Industry groups, including the U.S. Travel Association and IATA, have condemned the proposal, warning it could cause significant disruptions to international travel and economic losses estimated at billions of dollars. Some local officials, like New Jersey Governor Mikie Sherrill, have publicly opposed the plan, citing concerns about economic and security impacts.
Impact on International Travel and Economy
The plan, if implemented, could severely disrupt international travel, damage U.S. reputation abroad, and result in substantial economic losses, especially in cities that rely heavily on tourism and international visitors. It also raises questions about federal authority versus local policies and the potential for political conflicts to influence airport operations.

Background on Sanctuary Cities and DHS Enforcement
In April 2025, President Trump signed an executive order requiring the Department of Justice to identify jurisdictions that allegedly obstruct federal immigration enforcement. The DOJ designated 18 sanctuary cities, including New York, Chicago, and Newark, based on their policies and actions perceived as hindering immigration laws. Mullin’s plan appears to be a response to ongoing protests and local resistance at ICE detention facilities, particularly Delaney Hall in New Jersey.
This development follows previous tensions between federal immigration authorities and local jurisdictions, with Mullin emphasizing enforcement and local cooperation as key issues driving the proposed airport measures.
“The agency is currently drawing up plans for these sanctuary cities where local authorities aren’t allowing us to do our job and enforce federal laws.”
