With less than a month remaining until the 2026 midterm elections, a coalition of 34 Senate Democrats has delivered a stark warning to Homeland Security Secretary Markwayne Mullin. In a letter released on September 28, 2026, the lawmakers allege that the Department of DHS is employing immigration enforcement tools in ways that could suppress voter participation and breach constitutional protections.
The missive, spearheaded by Sen. Gary Peters of Michigan, the top Democrat on the Senate Homeland Security and Governmental Affairs Committee, bears the signatures of senior figures including Senate Minority Leader Chuck Schumer. The senators contend that recent DHS actions—ranging from ambiguous statements about deploying ICE and CBP officers near polling places to the use of a federal database to scan voter rolls for non-citizens—appear designed to erode public confidence in the electoral process.
Specific accusations against the Department of Homeland Security
The letter outlines several concrete concerns. First, the senators claim Secretary Mullin has failed to publicly assure that U.S. Immigration and Customs Enforcement (ICE) or Customs and Border Protection (CBP) will not be sent to voting sites, a move they argue could intimidate eligible voters, particularly immigrants. Although DHS has asserted that ICE “is not planning operations targeting polling locations,” it simultaneously maintains the right to conduct “intelligence-driven targeted enforcement” if a public-safety threat is identified at a precinct.
Second, the Democrats denounce the administration’s recent effort—backed by a Supreme Court decision granted late last week—to cross-check state voter rolls against a federal database believed to contain citizenship information. The senators question the accuracy of that database, noting that DHS has not substantiated its claim that roughly 250,000 potential non-citizens are registered to vote in four states.
Broader implications for federal funding and election integrity
Beyond direct voter intimidation, the letter raises alarms about the Department of FEMA withholding anti-terrorism grants from states that resist the administration’s new election policies. Democratic officials have already filed lawsuits challenging the funding freeze, arguing that it jeopardizes community resilience and undermines FEMA’s core mission.
Finally, the senators reference a whistleblower report describing an “Unlawful Voter Initiative” in which DHS personnel allegedly gain access to state voter data by falsely claiming voter status or authorization. If true, the practice could breach state laws and further disenfranchise voters, according to the Democrats’ assessment.
Responses from the Department of Homeland Security
In a brief statement to MS NOW, a DHS spokesperson dismissed the accusations as “totally false,” asserting that the agency is merely fulfilling its statutory duty to safeguard election infrastructure. The statement emphasized that any enforcement actions would be “targeted” and linked only to genuine public-safety threats, not to political considerations.
Nevertheless, the Democrats conclude their letter by demanding full disclosure of the data and rationale behind the alleged non-citizen registrations, an immediate halt to any deployment of immigration officers to polling sites, and the swift release of any withheld FEMA grants.
Sen. John Fetterman of Pennsylvania, a centrist Democrat, added his name to the warning, reinforcing the bipartisan concern that the Department of DHS should not become an instrument of election interference.
As the November vote approaches, the clash between congressional Democrats and the Trump administration’s immigration agenda underscores a broader struggle over who controls the mechanics of American democracy.
