The Department of Homeland Security (DHS) has partially shut down due to a funding lapse after lawmakers failed to reach an agreement on budgets, particularly related to Immigration and Customs Enforcement (ICE) reforms. Essential operations continue, but TSA agents are working without pay at U.S. airports, leading to potential travel delays. The situation escalates as pressure mounts on DHS leadership amid stalled negotiations, with the travel industry sounding alarms over the impact of the shutdown. Amidst the standoff, Democrats and the White House remain divided over provisions concerning immigration enforcement, raising uncertainties about the duration of the shutdown.
