The U.S. Department of Homeland Security (DHS) has entered a partial shutdown after a standoff between congressional Democrats and the White House failed to produce a funding agreement before the February 14 deadline, according to multiple news reports.

Lawmakers have been negotiating over DHS funding in the context of broader disputes related to immigration enforcement reforms, including demands from Democrats for changes to Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP) procedures.

Senate Democrats had opposed a funding bill that did not include restrictions they sought on immigration agencies, and a key Senate vote failed to reach the 60-vote threshold needed to advance the legislation, raising the likelihood of a shutdown.

While portions of the federal government remain funded, the lapse in DHS appropriations means that non-essential parts of the department — including some operations of FEMA, the Coast Guard and the Transportation Security Administration (TSA) — are affected, though many mission-critical staff continue working under contingency plans without pay.

The funding impasse reflects ongoing partisan tensions, with Democrats linking their support to reforms and Republicans arguing that failure to fund the department would hurt national security.
