A deepening partisan dispute over immigration enforcement kept the Department of Homeland Security (DHS) partially shut down Thursday after Senate Democrats blocked a Republican funding bill for the third time.
The Senate voted 51–45 to advance the measure, falling short of the 60 votes required to proceed. Earlier in the day, the House of Representatives passed a similar bill to fund DHS through September, but the Senate vote ensured the funding lapse — now nearing three weeks — would continue.
The stalemate reflects a broader clash between Republicans, who say Congress must immediately restore funding to protect national security, and Democrats, who insist new limits on immigration enforcement must be included in any spending bill.
Republican Argument: National Security Risks
Republican leaders say the shutdown is weakening the nation’s security posture and argue that DHS should be funded without attaching policy changes.
Senate Majority Leader John Thune, R–S.D., warned that the lapse in funding has already disrupted some functions within the department.
“Less than half of the Americans who work for the Cybersecurity and Infrastructure Security Agency are on the job,” Thune said. “The rest have been furloughed, and the agency has had to cancel vulnerability checks on certain infrastructure.”
Republicans have also pointed to the escalating conflict involving Iran as a reason to move quickly.
“It shouldn’t need saying that it’s always a terrible idea to use the Department of Homeland Security as a political pawn,” Thune said. “But above all right now, with enhanced terror threat from Iran and Iran-funded terrorist groups, it is vital that we ensure the Department of Homeland Security is fully funded and fully functioning.”
House Speaker Mike Johnson, R–La., said the international situation makes resolving the impasse even more urgent.
“The military action in Iran makes it all the more urgent and crucial to have a fully staffed, fully funded Department of Homeland Security across all departments,” Johnson said, accusing Democrats of “playing political games” by opposing the legislation.
Republicans have urged Democrats to support a bipartisan appropriations agreement negotiated earlier this year that would fund DHS through the end of the fiscal year.
Democratic Position: Immigration Enforcement Reforms
Democrats say they will not support even a temporary funding measure unless it includes new safeguards governing immigration enforcement operations.
All but one Democrat—Sen. John Fetterman of Pennsylvania—voted against advancing the Republican proposal.
Democratic lawmakers argue reforms are necessary after controversies surrounding immigration enforcement activities, including a fatal shooting involving federal agents in Minneapolis earlier this year.
Their proposals include requiring immigration agents to display visible identification, limiting the use of masks during operations and imposing stricter use-of-force standards.
Sen. Patty Murray, D–Wash., the top Democrat on the Senate Appropriations Committee, said Democrats also suggested moving forward with funding for other DHS operations while negotiations continue over immigration enforcement policies.
“If Republicans keep refusing to ensure ICE and Border Patrol follow the same basic standards that police departments across America already follow,” Murray said, “then we should at least fund TSA and FEMA while we press on with negotiations.”
Republicans objected to that proposal.
Negotiations Amid Leadership Change
Negotiations between Democrats and the White House over possible enforcement reforms have been underway for weeks, though there have been few signs of a breakthrough.
President Donald Trump added a new dimension shortly before the Senate vote by announcing he was replacing DHS Secretary Kristi Noem.
Trump announced that he will nominate Republican Sen. Markwayne Mullin of Oklahoma to lead the Department of Homeland Security.
Some Democrats indicated the leadership change could help break the stalemate.
Sen. Richard Blumenthal, D–Conn., suggested earlier that negotiations over DHS funding might become easier if the department’s leadership changed. However, he noted that “changing only the top official is inadequate without changing the practices and power structure in the department.”
Shutdown Effects
Despite the lapse in funding, DHS continues to carry out what it considers essential missions. However, many employees—including Transportation Security Administration officers—are working without pay until funding is restored.
The shutdown has had fewer immediate operational consequences for immigration enforcement agencies because Immigration and Customs Enforcement and Customs and Border Protection have access to billions of dollars in previously approved funding that is not dependent on the current DHS appropriations bill.
With both parties standing firm on their demands, the impasse appears likely to continue, leaving the department partially shuttered while negotiations carry on.
