The Department of Homeland Security (DHS) shut down at 12:01 a.m. Saturday after Congress failed to pass funding legislation, leaving many core operations in limbo. While most DHS employees deemed necessary for safety and security continue working without pay, non-essential functions and administrative tasks face furloughs or disruption. Agencies like the Coast Guard, Cybersecurity and Infrastructure Security Agency, and TSA are affected, potentially leading to longer airport security lines and delays in certain services.

Despite the shutdown, immigration enforcement will largely continue, supported by last year's $165 billion funding boost, including significant funds for ICE and CBP. Secret Service protective duties remain operational, and counterterrorism surveillance is unaffected. However, functions such as FEMA disaster assistance could experience delays, and some DHS operations may be temporarily limited if the shutdown persists beyond the holiday weekend. The impasse highlights ongoing disagreements over immigration policies and funding priorities, with official efforts ongoing to seek bipartisan solutions.
