The Trump administration is reportedly drafting plans to stop immigration and customs processing at airports located in sanctuary cities, including major hubs such as Los Angeles, New York, and Chicago. DHS Secretary Markwayne Mullin has indicated that these measures could target up to ten major airports, potentially crippling international travel and impacting the economies of these cities. The announcement has sparked widespread concern within the travel industry, which fears chaos and significant disruptions as millions prepare for upcoming events like the World Cup. Experts have also warned that such moves could violate legal standards and further escalate tensions surrounding immigration policy in blue cities.
