As Washington threatens to slash customs officers at airports in sanctuary cities, California leaders warn that the federal government is now willing to weaponize international travel itself in the immigration wars.

Story Snapshot

• The Trump administration is weighing cuts to U.S. customs services at international airports in sanctuary jurisdictions, potentially snarling travel and local economies.
• Governor Gavin Newsom signals he is prepared to fight the move in court, building on a long record of California lawsuits challenging Trump-era immigration and emergency powers.^[1][4][5]
• The Department of Homeland Security frames the idea as a lawful way to pressure cities that limit cooperation with federal immigration enforcement.
• Both conservatives and liberals see the fight as fresh evidence that Washington’s power struggles are punishing ordinary Americans more than political elites.

Trump Administration Floats Customs Cutbacks Tied to Sanctuary Policies

Federal officials in the Trump administration are considering scaling back customs and border inspection operations at international airports located in so‑called sanctuary cities, including major hubs in California. Reports describe an internal Department of Homeland Security proposal to reduce U.S. Customs and Border Protection staffing or services as leverage on jurisdictions that limit cooperation with federal immigration enforcement. Such reductions could lengthen wait times, disrupt business travel, and discourage tourism, effectively using airport bottlenecks as a pressure point in an ongoing federal‑state immigration showdown.

News coverage indicates that the Department of Homeland Security concept fits a broader strategy: conditioning federal benefits or services on local compliance with immigration priorities, similar to earlier efforts to tie grant funding to cooperation with federal immigration agents.^[5] Unlike funding disputes, however, customs operations are a direct federal responsibility that international travelers depend on, so using them as leverage would make the costs of political conflict highly visible to businesses, workers, and families who rely on efficient international gateways.

Newsom Signals Legal Fight, Citing California’s Sanctuary Track Record

Governor Gavin Newsom has already been asked publicly how he would respond if customs officers were pulled from California’s international airports, and he signaled strong opposition and a willingness to fight back. California previously challenged Trump administration actions targeting sanctuary policies, including federal attempts to penalize non‑cooperating jurisdictions by threatening funds, and those cases produced mixed but significant limits on federal leverage.^[3][5] Legal advocates note that California’s sanctuary framework is structured as a refusal to assist, not an effort to block federal agents from doing their jobs.^[3]

California’s broader record against Trump’s second‑term initiatives suggests that any airport‑services cut could quickly land in court.^[1][4][5] In Newsom v. Trump, the state sued over the federalization and deployment of the California National Guard during immigration‑related protests, arguing that the President unlawfully commandeered state military resources.^[4][5] A federal judge ultimately ruled that parts of the deployment violated the Posse Comitatus Act and barred the use of National Guard troops for civilian law enforcement in California, even as appeals left some issues unresolved.^[4][5] That experience has reinforced California’s view that federal power in these fights has real limits.

Legal Grey Zones and the Risk of Punishing Travelers, Not Politicians

Legal scholars observing sanctuary disputes describe a recurring pattern: Washington uses carrots and sticks tied to immigration cooperation, while states insist they can decline to help without obstructing federal enforcement.^[5] Prior litigation has focused heavily on federal grants or conditions placed on local law enforcement cooperation, not on customs operations at international airports.^[5] The available record does not yet show a primary Department of Homeland Security order spelling out how customs reductions would work or what legal theory would justify targeting specific airports for service cutbacks.

Dems keep getting dumber.
"Trump needs to know we will not stand idly by while he investigates crimes that benefit us," Newsom said at the bill signing. "Only dictators do that."

For Americans across the political spectrum, the emerging fight highlights a deeper frustration: federal power struggles increasingly spill over onto everyday life while political and economic elites remain insulated. Conservatives who support tougher immigration enforcement may still balk if business travelers, exporters, and working families get stranded in airport lines as collateral damage. Liberals who back sanctuary policies see a pattern of federal retaliation aimed at punishing dissenting cities rather than fixing the underlying immigration system.^[3] In both cases, the perception grows that Washington’s battles are about flexing power, not delivering competent, accountable governance.
