The partial shutdown of the Department of Homeland Security entered its 44th day on Sunday, becoming the longest such funding lapse in U.S. history.

The current standoff surpasses the previous record shutdown and stands out because it affects only DHS, while the rest of the federal government remains funded.

Efforts to resolve the impasse stalled further on Friday after House Republicans passed a short-term funding bill that is unlikely to advance in the Senate. The vote came just hours after the Senate approved a bipartisan measure to fund most of DHS, excluding Immigration and Customs Enforcement and parts of Customs and Border Protection.

House Speaker Mike Johnson rejected the Senate proposal, calling it insufficient, while the House bill faces steep hurdles in the Senate, where 60 votes are required to move forward. Republicans, who hold a narrow majority, would need Democratic support to pass any funding measure.

Democrats have insisted on adding restrictions to immigration enforcement practices before agreeing to fully fund DHS, a demand Republicans have resisted, leaving negotiations at a standstill.

The prolonged shutdown is already having visible consequences. Airport security operations have been strained as Transportation Security Administration officers continue working without pay, leading to staffing shortages, long security lines, and increased absenteeism.

In response, President Donald Trump signed an order Friday directing DHS to issue paychecks to TSA workers, with payments expected to begin as early as Monday.

Despite that step, lawmakers remain deadlocked, and no clear resolution to the shutdown is in sight.
