Denver, Voting Rights Groups Sue to Block ICE Agents at Polling Sites

The city of Denver and a coalition of national civil rights organizations filed a first-of-its-kind lawsuit on Thursday asking a federal judge in Washington, D.C., to bar armed Immigration and Customs Enforcement agents from approaching polling sites during the midterm elections.

The preemptive challenge, filed in the U.S. District Court for the District of Columbia, targets what the coalition calls an emerging "Polling Place Policy" -- a set of federal plans the groups say would put armed officers within reach of voters as early voting begins later this month.

"The specter of armed officers at polling places threatens the freedom of this upcoming election," the filing states. "It places voters in fear that they will be confronted by armed federal law enforcement if they choose to cast a ballot."

A Civil War-Era Statute at the Center of the Case

The lawsuit leans heavily on 18 U.S. Code Section 592, a Reconstruction-era law Congress passed in 1865 to stop a president from using federal force to influence elections. The statute criminalizes ordering "any troops or armed men" to a place where a general or special election is being held.

Lawmakers narrowed the law further in 1909, stripping out an exception that had allowed federal authorities to station personnel at the polls to "keep the peace." The coalition argues that history shows Congress intended to keep armed federal agents away from the ballot box except in the most extreme circumstances.

The statute allows only one narrow carve-out: deploying troops to repel an attack by "armed enemies of the United States" at a specific site. The filing argues that even then, the law authorizes defense against an attack -- not routine law enforcement.

Denver filed the suit alongside the League of United Latin American Citizens, Common Cause and UnidosUS, with the legal group Democracy Forward representing the coalition. The complaint names the Department of Homeland Security and ICE, as well as their leaders, Secretary Markwayne Mullin and David Venturella.

The groups are asking the court to declare that the federal government has no authority to send armed officers to polling locations, and to prohibit federal agents from carrying weapons near voting sites, ballot drop boxes and curbside voting locations.

Administration Says Agents Aren't There to Patrol the Polls

Homeland Security officials have repeatedly pushed back on the idea that ICE would be used to intimidate voters, describing any presence at polling sites as narrow and threat-driven.

"ICE isn't there to patrol the polling places," Secretary Mullin said at a news conference in New York City this month. He added that agents could be present only if there is a threat to a site or if they are serving a warrant. "If we're serving a warrant, we will be where we need to be," he said.

The administration's broader election push has focused on verification and integrity. An executive order signed in April, "Ensuring Citizenship Verification and Integrity in Federal Elections," directs agencies to build lists of citizens eligible to vote and instructs the U.S. Postal Service to deliver mail ballots only to verified voters.

That effort survived an early legal test. The Supreme Court on Aug. 24 declined to block the mail-in voting changes, finding that challenges were premature because no formal policy had yet taken effect. The Postal Service published its final rule on Aug. 27.

Months of Escalation Set the Stage

The coalition points to a series of public signals it says amount to an unwritten policy. It cites comments from then-Deputy Attorney General Todd Blanche at the Conservative Political Action Conference, where he questioned why anyone would object to sending ICE officers to polling places.

Soon after, the Justice Department removed a long-public manual that stated federal agents are barred from patrolling polling sites under the Civil War-era statute, the groups say.

The filing also highlights incidents over the summer in San Antonio, Ventura County, California, and Syracuse, New York, where ICE agents entered active polling locations. The coalition treats those episodes as evidence that a policy is already being carried out.

Gen. Dan Caine, chairman of the Joint Chiefs of Staff, has said the military has no plans to dispatch troops or National Guard soldiers to polling places -- a distinction the coalition does not dispute but says does not resolve the ICE question.

What to Watch as Early Voting Nears

The case faces a familiar hurdle: courts have been reluctant to intervene before a formal policy exists. The administration is expected to argue that the lawsuit is speculative, since no published rule orders agents to polling sites.

The coalition counters that the pattern of statements and on-the-ground incidents shows the policy is real and already operating. It warns that waiting for a formal document could leave voters facing armed officers before any judge rules.

A ruling could land quickly given the calendar. Early voting starts within weeks, and any injunction -- or refusal to grant one -- would reshape how federal agencies approach the polls in November.

For now, the fight sets up a rare collision between a 161-year-old statute written to protect the ballot box and a modern administration arguing that its election-security measures are lawful, targeted and necessary to protect the integrity of American elections.
