Homeland Security Secretary Markwayne Mullin has questioned whether cities with international airports that do not cooperate with the Department of Homeland Security should face repercussions, such as losing access to customs processing. Mullin, who was recently confirmed as the secretary, suggested that if they're a sanctuary city, they should focus on cities that want to cooperate and enforce immigration policy. His comments align with those of his predecessor, Kristi Noem, who led immigration enforcement operations in blue-led cities and publicly identified 500 cities, counties, and states that are obstructing the enforcement of immigration laws. The Senate recently passed a bill that would fund most of DHS, excluding Immigration and Customs Enforcement (ICE) and Border Patrol, but House Republicans rejected this proposal.
