The Department of Homeland Security remains without approved funding as Senate Democrats on Thursday blocked a Republican-backed bill aimed at financing the agency through the end of fiscal year 2026. The vote, 51-45, fell short of the 60 votes required to advance the measure, leaving the agency in its fourth week of a partial shutdown.

Every Democrat opposed the legislation except John Fetterman. Republicans argued that recent tensions with Iran and other national security threats make restoring DHS operations urgent.

Democratic senators countered that DHS had already received significant funding in a previous spending package and pressed for reforms to immigration enforcement before approving additional resources. Tim Kaine told The Hill that the agency “has plenty of money” and that Democrats would not forgo necessary policy reforms.

Democrats are calling for new restrictions on Immigration and Customs Enforcement and Customs and Border Protection operations, including stricter warrant requirements and rules requiring agents to be identifiable during enforcement actions.

The standoff highlights the growing partisan divide. Senate Majority Leader John Thune accused Democrats of refusing to negotiate in good faith, while Senate Minority Leader Chuck Schumer said Republicans could end the impasse by agreeing to the proposed reforms.

The funding dispute has coincided with ongoing scrutiny of DHS operations, including controversial ICE enforcement actions in Minnesota that have sparked protests and intensified the national debate over immigration policy.

The impasse also comes amid leadership changes at the department. President Donald Trump announced plans Thursday to replace DHS Secretary Kristi Noem with Markwayne Mullin, signaling additional shifts in department priorities.
