Trump's new Homeland Security Secretary, Markwayne Mullin, proposed during a Fox News interview that the administration might remove customs processing from international airports in "sanctuary cities." The threat targets cities where local authorities limit cooperation with federal immigration enforcement, including Boston, Chicago, Denver, Los Angeles, New York, Newark, Philadelphia, Seattle, and San Francisco. Mullin framed this as a potential consequence of defunding Customs and Border Patrol, suggesting the administration must prioritize cities willing to partner on immigration policy. While no official policy change has been enacted, the threat signals a potential disruption to international flight operations at some of the country's busiest hubs
