The US Justice Department has filed an unusual lawsuit seeking to prevent Alaska from certifying its Senate election results under a specific scenario in which Republican incumbent Dan Sullivan narrowly loses to Democrat Mary Peltola, opening a legal battle over voter confusion, ballot secrecy and federal authority over state-run elections just days before the November 3 midterms.
President Donald Trump confirmed on Friday that he personally directed the Justice Department to pursue the legal challenge, which could affect the balance of power in the Senate if the Alaska contest proves decisive.
The lawsuit, filed in federal court on Thursday, targets the candidacy of Dan J. Sullivan Jr., a second Republican whose name closely resembles that of the incumbent, Senator Dan S. Sullivan. The Justice Department argues that the additional candidacy could confuse voters intending to support the sitting senator and divert votes that might otherwise determine the outcome.
The department has asked a federal judge to prevent Alaska from certifying the result if the incumbent loses by fewer votes than the total received by his same-named challenger. Under that scenario, the court would be asked to investigate whether voter confusion affected the outcome.
The legal action places the administration at the centre of a dispute over an election that has not yet taken place. It also raises a broader question for the 2026 midterms: under what circumstances can the federal government seek to intervene in a state’s election certification process?

Trump acknowledged his role in the lawsuit while speaking to reporters in Florida on Friday.
“I’m the one that said do it,” he said, according to The Washington Post.
The president had criticised the second Sullivan’s candidacy on social media earlier in the week, describing it as a “SCAM” and indicating that his administration was considering legal options.
Justice Department officials have defended the intervention as an effort to protect electoral integrity. Associate Attorney General Stanley E. Woodward argued in the court filing that the second candidate’s presence could mislead voters and distort the electorate’s intentions.
The department’s case relies on the National Voter Registration Act, a federal law governing voter registration. Justice Department lawyers have invoked language in the statute concerning the protection of the integrity of the electoral process to justify federal involvement.
However, the legal theory has drawn criticism from election-law specialists, who question whether the statute provides a sufficient basis for blocking certification under the circumstances described in the lawsuit.
The Washington Post reported that legal experts also questioned how investigators could determine whether voters had confused the two candidates without compromising the secrecy of individual ballots.
The department has not established that the election result will be affected by the second candidacy. The lawsuit instead seeks a judicial mechanism to examine a potential outcome if the margin between the incumbent and Peltola is smaller than the votes received by Dan J. Sullivan Jr.
The distinction matters because the proposed intervention would be conditional on a future result. It is not evidence that voter confusion has already changed the outcome, nor does the lawsuit establish that the second candidate’s votes were cast by people who intended to support the incumbent.
Attorney General Todd Blanche sought to distance the department from any suggestion that it intended to interfere improperly with state certification procedures. Speaking on Thursday, he said the department did not intend to interfere with elections, while declining to rule out intervention in every possible circumstance.
A Justice Department spokesperson subsequently said the department was taking steps to ensure that what it described as a frivolous candidacy did not undermine the integrity of Alaska’s election.
Peltola’s campaign condemned the lawsuit, calling it a political threat and an attempt to suppress Alaskans’ votes. The campaign said it would fight to ensure that every eligible voter could participate.
The incumbent senator’s campaign said it was prepared to let the legal proceedings continue. It also defended Sullivan’s record in office.
The competing responses underline the political sensitivity of the case. A ruling that delays certification could affect the timing of the Senate result, while the ultimate legal outcome would depend on the court’s assessment of the department’s statutory arguments and the circumstances of the election.
Second Sullivan’s candidacy has faced legal challenges since June
The dispute predates the Justice Department’s intervention. Dan J. Sullivan Jr., a retired teacher and former member of the Alaska Independence Party, registered as a Republican shortly before entering the Senate race this year. He has denied attempting to mislead voters or coordinating with Democrats or Peltola’s campaign.
Alaska election officials moved in June to remove him from the ballot, agreeing with concerns that his candidacy could confuse voters. A state court subsequently ordered that he be reinstated, and the state’s Supreme Court later upheld that decision.
He advanced to the general election through Alaska’s August primary, which sends the top four candidates to the general election regardless of party affiliation. He received approximately 2.5% of the primary vote, according to The Washington Post.
Name confusion involving candidates is not unprecedented in Alaska. The newspaper reported that Senator Dan S. Sullivan was first elected in 2014, when another politician named Dan Sullivan, then Anchorage’s mayor, was running for lieutenant governor. An Alaska political consultant told the newspaper that confusion over the names may have contributed to the senator’s victory that year.
The present dispute, however, involves a distinct legal question: whether the possibility of voter confusion provides a sufficient basis for a federal court to stop certification if the eventual vote margin meets the condition outlined in the lawsuit.
Election-law experts quoted by The Washington Post criticised the department’s legal reasoning. University of Notre Dame law professor Derek T. Muller questioned its interpretation of the voter-registration statute, while David Becker, executive director of the Center for Election Innovation & Research, said he could not recall an administration attempting to stop certification so close to an election.
The lawsuit also leaves unresolved how an investigation into voter intent could be conducted without identifying individual ballot choices. That issue could become central if the court allows the case to proceed.
Why the Alaska case matters for control of the Senate
Alaska is one of six Republican-held Senate seats identified in Reuters’ midterm analysis as being in play, alongside Maine, North Carolina, Ohio, Iowa and Texas. Democrats need a net gain of four seats to take control of the Senate, while also defending competitive contests in Michigan and New Hampshire.
That arithmetic gives the Alaska lawsuit significance beyond the state itself. If the Senate’s balance ultimately depends on the result, a delay in certification could become part of a wider national dispute over which party controls the chamber.
Alaska’s use of ranked-choice voting and its comparatively lengthy tabulation process could also create additional opportunities for legal challenges, election-law specialists have warned, according to The Washington Post.
The lawsuit comes amid broader disputes between the Trump administration and state election authorities. The administration has sought greater federal involvement in election administration, challenged state voter-registration practices and pursued restrictions concerning mail ballots. Several of those efforts have encountered legal resistance.
The administration’s critics argue that attempts to intervene in state election processes risk undermining public confidence, particularly when action is directed at a race that could determine control of Congress. The Justice Department maintains that its intervention is intended to protect election integrity.
Those positions will ultimately be tested against the law, the evidence and the court’s decision. The existence of a same-named candidate, by itself, does not establish that voters have been misled or that an election result is invalid.
The Alaska case also highlights the difference between counting votes, determining whether election rules have been followed and certifying the official result. Certification is the formal process through which election authorities confirm the outcome after required procedures have been completed. A court order blocking certification would interrupt that process, but would not itself establish who won the election.
With Election Day approaching on November 3, the immediate question is whether the federal court will accept the Justice Department’s argument that the potential for confusion justifies conditional intervention in the certification process.
The broader stakes extend beyond one Senate contest. The case will test the boundaries of federal authority over state elections and how courts address allegations that a candidate’s name could influence voting behaviour. It will also provide a closely watched example of how election disputes may unfold if control of Congress depends on a narrow result.
For now, the lawsuit concerns a possible outcome, not a proven case of electoral interference. Whether it results in a certification delay will depend on the court’s ruling and the eventual vote count in Alaska.
