After weeks of stalled negotiations, lawmakers in Congress are working on a partial funding plan for the Department of Homeland Security as a prolonged shutdown strains airport operations and security.

The proposal, backed by Republicans, would fund most of DHS but exclude key immigration enforcement operations, which Democrats oppose without major reforms to Immigration and Customs Enforcement.

Donald Trump has also resisted the deal, insisting it include the SAVE America Act, a controversial elections overhaul lacking sufficient Senate support.

Meanwhile, the shutdown—now over a month long—has led to severe Transportation Security Administration staffing shortages, long airport lines, and unpaid federal workers, NPR has reported.

With Democrats, Republicans, and the White House divided, a resolution remains uncertain despite ongoing negotiations.
