Graham Platner has suspended his campaign for the U.S. Senate in Maine and announced plans to remove his name from the ballot, ending a campaign that faced mounting political pressure and controversy.

In a video statement released Wednesday, Platner said stepping aside was necessary to allow the movement behind his campaign to continue, while insisting the decision should not be viewed as an admission of guilt.

The announcement comes days after a woman who previously dated Platner publicly accused him of sexual assault. Platner has strongly denied the allegation, maintaining that it is false. Despite defending himself, the controversy prompted several prominent Democratic figures and major campaign donors to withdraw their support, leaving his candidacy increasingly difficult to sustain.

Platner said the campaign's suspension was driven by the loss of political and organizational backing rather than the accusations themselves. He reiterated that he rejects the claims against him and intends to continue defending his reputation.

His departure creates a major opening in one of the country's most closely watched Senate contests. Democrats had hoped to challenge longtime Republican Sen. Susan Collins, viewing the Maine race as a key opportunity in their effort to regain control of the U.S. Senate during the 2026 midterm elections.

Following Platner's decision, Maine Democratic Party leaders voted during an emergency meeting to hold a nominating convention to choose a replacement candidate. Party officials said further details, including the convention schedule, will be announced in the coming days.

State election law requires Democrats to select a new nominee by July 27 for the candidate to appear on the November general election ballot.

Several Democrats are already being mentioned as possible replacements, including former Maine Senate President Troy Jackson, former state public health official Nirav Shah, and Maine Secretary of State Shenna Bellows.

The selection of a new Democratic nominee is expected to reshape the race, with national attention focused on whether the party can mount a competitive challenge against Collins in one of the most significant Senate elections of the year.
