This is going to shake up the entire nation.
The Trump administration is escalating its battle with sanctuary cities, and the latest warning from the Department of Homeland Security could have major consequences for international travel and immigration enforcement across the country.
Homeland Security Secretary Markwayne Mullin said Tuesday that cities and states refusing to cooperate with federal immigration authorities may eventually lose key customs and immigration processing support at their international airports.
During an interview with Sean Hannity on Fox News, Mullin argued that local governments cannot continue blocking federal immigration enforcement while still expecting full federal support for airport operations involving international travelers.
According to Mullin, the administration is reviewing options in jurisdictions where local officials limit cooperation with Immigration and Customs Enforcement. He suggested that if federal immigration officers are prevented from carrying out deportation enforcement and public safety operations, the federal government may reconsider how immigration services are handled at those airports.
The discussion could directly affect some of the nation’s busiest travel hubs, including JFK Airport, LaGuardia Airport, and Newark Liberty International Airport. Together, those airports process tens of millions of international passengers every year.
Supporters of the proposal say sanctuary city policies have created unnecessary obstacles for federal law enforcement and weakened immigration enforcement efforts nationwide. Critics, however, warn that changes to airport customs operations could disrupt travel and create economic concerns for major metropolitan areas.
Transportation Secretary Sean Duffy has reportedly expressed concerns about tying airport operations to political disputes between local governments and federal agencies. Airline industry organizations have also voiced opposition, warning that large-scale disruptions at international airports could impact travelers, airlines, and local economies.
The debate comes as protests continue outside the Delaney Hall detention facility in Newark, New Jersey. Demonstrators have gathered in recent days to protest conditions inside the immigration detention center, while federal officials say many claims circulating online are inaccurate.
The Department of Homeland Security released a public statement defending conditions inside the facility, saying detainees are being provided meals, water, hygiene products, bedding, and access to communication with attorneys and family members.
Trump border czar Tom Homan also defended the administration’s handling of immigration detention facilities and indicated that the federal government may expand the use of federally controlled detention centers located on government-owned land.
According to Homan, the strategy would reduce conflicts with local jurisdictions that refuse to cooperate with federal immigration enforcement efforts.
For years, many sanctuary jurisdictions have declined to honor ICE detainer requests, which ask local authorities to temporarily hold illegal immigrants accused or convicted of crimes so federal agents can take custody for possible deportation proceedings.
Supporters of President Donald Trump argue that stronger immigration enforcement is necessary to improve border security, reduce crime, and restore federal authority. Opponents say sanctuary policies help build trust between immigrant communities and local law enforcement.
As the national immigration debate intensifies ahead of the 2026 elections, the Trump administration appears determined to increase pressure on sanctuary cities while continuing to make border security a major political priority.
