The travel industry is reacting with concern after U.S. Homeland Security Secretary Markwayne Mullin reiterated a threat to withdraw U.S. Customs and Border Protection (CBP) officers from airports located in so-called “sanctuary cities.” Multiple outlets report that the administration is weighing steps that would reduce or remove CBP staffing at these airports, which handle international passenger processing and cargo operations. Such changes, they say, could disrupt international flights and related commerce, particularly at major airports in Democratic-leaning areas. One report additionally describes the administration as drawing up plans that could halt processing of international travelers and cargo at selected “sanctuary city” airports. The outlets frame the issue as a potential operational and economic risk for airlines, airport operators, and downstream travel businesses, depending on what actions are taken and how broadly they apply. The reports emphasize that the administration’s proposal targets airports associated with jurisdictions that have declined to cooperate with aspects of an immigration crackdown, and that the threat centers on the presence or withdrawal of CBP resources rather than on an immediate nationwide travel ban.
