Graham Platner, the Democratic nominee for Senate from Maine, said he was taking time to “reflect” on his political path forward as his support swiftly eroded after a woman accused him of rape.
In a video posted on social media, Mr. Platner called the account “false” even as he acknowledged the threat it posed to his candidacy in a tight race that could determine control of the Senate in November.
“Regardless of the inaccuracy of the reporting but mindful of the political reality it will inflict, we are taking the time to reflect on the best path forward,” he said.
It was not immediately clear whether Mr. Platner intended to continue his campaign against Senator Susan Collins, a Maine Republican. He has until July 13 to withdraw from the race, and if he does the state Democratic Party has until July 27 to replace him on the ticket, according to Maine state law. The leadership of the state party urged him to withdraw.
Both parties see Maine as key to the battle for control of the Senate, and prominent Democrats withdrew their endorsements of him after the allegations surfaced.
The Senate Democratic campaign arm, which had opposed Mr. Platner in the primary, called for him to quit the race. “Graham Platner needs to immediately withdraw as the Democratic nominee for Senate and allow Maine Democrats the opportunity to choose a new candidate who can defeat Susan Collins,” a statement from Senators Chuck Schumer and Kirsten Gillibrand of New York said. “The D.S.C.C. will not invest in the Maine Senate race if Platner remains on the ballot.”
Some of his key supporters called for him to drop out as well, including Senator Elizabeth Warren, who had championed his bid. “There can be no tolerance for sexual assault,” she said in a statement. “With so much at stake, the best path forward is for Graham Platner to step aside as the Democratic nominee and address these serious allegations outside this Senate race.”
Representative Ro Khanna, a California Democrat who had been another key backer, also withdrew his support. “These allegations are very serious and credible,” he said. “Graham Platner should drop out from the race. I am withdrawing my endorsement.”
There were some indications that Mr. Platner may be contemplating an exit.
He has not made a decision on whether to drop out, according to a person familiar with the campaign’s internal discussions, who added there was no guarantee he would drop out even as Democrats abandoned his campaign. “If he was to step down it would only be with a guarantee of being replaced by a candidate who he believes is true to the values and vision and policy agenda of the campaign that Maine voted for,” said the person, who was granted anonymity because they were not authorized to speak about the discussions publicly.
The accusation was made by Jenny Racicot, who said she dated Mr. Platner casually off and on between 2019 and 2021. She told The New York Times this spring about a 2021 incident in which she said he arrived at her house drunk after she had asked him not to come over. At the time, she declined to share further details of that encounter on the record, but she said she found his behavior “reckless” and “unsettling,” and cut off contact soon after that episode.
But in a new interview published in Politico on Monday, Ms. Racicot elaborated on her recollection of that night, saying Mr. Platner let himself into her home, climbed on top of her and kept grabbing her — even after she repeatedly told him to stop. He ignored her protests and followed her into the bedroom, where, she said, he had sex with her against her will.
“I had been telling him these words, like: ‘No, don’t,’” she told Politico.
“And, the look on his face and realizing what was happening, I just realized that, like, I am in a situation where there’s no consent here,” she said.
Later, on CNN, Jake Tapper asked Ms. Racicot: “Did Graham Platner rape you?”
She responded: “By definition, yes, absolutely.”
Ms. Racicot did not immediately respond to a request for comment.
Mr. Platner called the allegations “troubling, serious, and false,” in the direct-to-camera video.
“Any accusation of non-consensual behavior is categorically false,” he said.
His statement came shortly after he had postponed several campaign events.
Senator Collins, who is seen as one of the most vulnerable incumbent Republicans in the Senate, said in a statement that the “allegations are appalling.” But she added that “it is not up to me to choose the Democratic nominee for Senate.”
Several local and national elected officials withdrew their support of Mr. Platner on Monday.
State Senator Mattie Daughtry, a Democrat and the president of the Maine Senate, said in a statement that Mr. Platner should exit the race, describing the allegations against him over the last month as “serious” and saying that “sexual violence has absolutely no place in our society, and it cannot be tolerated from those seeking our highest positions of power.”
Senator Ruben Gallego, a Democrat of Arizona, said in a social media post that he was rescinding his endorsement of Mr. Platner, calling the allegations against him “troubling and deeply serious.”
And Donna Brazile, a former chair of the Democratic National Committee, suggested in a social media post that it was time for Mr. Platner to end his campaign. “Sure, take the rest of the day and night,” she wrote on X. “Tomorrow, we need a plan and Mr. Platner can step aside and focus on his family and well-being.”
One official who remained silent about the race on Monday was Senator Bernie Sanders of Vermont, a critical early supporter who appeared at campaign rallies with him. Mr. Sanders said nothing about Mr. Platner on social media, and aides did not immediately respond to messages seeking comment.
