J Street, the progressive Israel advocacy group, is for now withholding an endorsement of Graham Platner, the scandal-plagued Democratic Senate nominee in Maine, underscoring the extent to which even some left-wing Jewish activists appear skeptical of his insurgent campaign.

A spokesperson for J Street told Jewish Insider on Wednesday that the group did not “have anything to share at this time” about a Platner endorsement but would provide more information “if that changes.”

The spokesperson declined to confirm if J Street, which this cycle has backed a handful of Democratic Senate candidates vying for open seats or challenging Republican incumbents, had considered whether it will make an endorsement. The group had told JI in early May that it did “not currently have a position in the race.”

In a statement to JI on Thursday, the spokesperson said that it “is incorrect to frame J Street as actively withholding an endorsement from Graham Platner.” 

The group “evaluates candidates and makes endorsement decisions on a rolling basis,” and its “endorsement process is ongoing,” the spokesperson said. “The timing of endorsement decisions does not reflect judgment about any individual candidate.”

J Street’s response came after Platner had clinched the nomination on Tuesday to challenge Sen. Susan Collins (R-ME), in a high-profile race Democrats see as crucial to reclaiming control of the upper chamber.

Platner won the Democratic primary decisively even as he has faced a mounting series of controversies over alleged “toxic” relationships with past girlfriends, sexual messages he sent to women while married and deleted Reddit comments expressing a range of incendiary views.

He also weathered a scandal relating to a Nazi tattoo on his chest for nearly two decades that he covered up last October. Platner has insisted that he did not recognize its imagery, despite claims to the contrary from a former girlfriend who first spoke with JI last year, shortly after he had announced his campaign.

The tattoo, along with Platner’s hostile criticism of Israel and insistent demonization of AIPAC, have stoked ongoing concerns among Jewish Democrats. Halie Soifer, CEO of the Jewish Democratic Council of America, has said the group is not ready to endorse Platner.

“We won’t support a Democrat who doesn’t represent the views and values of the vast majority of American Jews,” Soifer said in a statement in late April echoing a sense of discomfort with Platner’s candidacy felt by mainstream Jewish leaders.

JDCA had endorsed Maine Gov. Janet Mills, who suspended her campaign amid lackluster fundraising but remained on the ballot Tuesday, pulling in 19% of the vote. Platner won 72%.

Following Tuesday’s win, some prominent Senate Democrats have also declined to endorse Platner as he prepares for a bruising and expensive campaign.

J Street, which has moved to the left in recent years as it has sought to capitalize on growing Democratic frustration with Israel, is in many ways aligned with Platner on Middle East policy, including accusations that Israel committed genocide in its war in Gaza and calls to block U.S. military aid to the Jewish state that are now gaining momentum in Congress.

Still, the group has shown its intolerance for some extreme views that could be seen as antisemitic. In 2024, for instance, J Street revoked its endorsement of former Rep. Jamaal Bowman (D-NY), who was at the time fighting for reelection in a bitterly contested primary he would later lose, saying his inflammatory rhetoric on Israel had crossed a line. 

Even as the group officially stays on the sidelines in Maine’s marquee Senate race, J Street’s state leader, Steven Koltai, who helped organize a Passover Seder with Platner, told the Jewish Telegraphic Agency he is “still very much” supporting the oyster farmer and former Marine in spite of recent revelations about his past.

In the statement to JI on Thursday, J Street’s spokesperson said the group “remains steadfast in our commitment to ensuring a pro-Israel, pro-peace majority in the Senate and House come January.”
