Top Platner ally turns on him after bombshell rape allegation rocks campaign: 'Red line'

Support for embattled Maine Senate candidate Graham Platner is cratering among Democrats, with one of his most prominent supporters calling on him to exit the race following a harrowing rape allegation.

Rep. Ro Khanna, D-Calif., rescinded his endorsement and called on Platner to suspend his campaign following a bombshell Politico report detailing a rape allegation by Maine resident Jenny Racicot, 41, who previously dated the scandal-plagued candidate.

Platner immediately denied Racicot's account — which alleges that he barged into her home in 2021 and forced her to have unprotected sex — but has said his campaign is determining its next steps.

"I’ve been very clear that sexual assault or violence against women is a red line," Khanna said in a post on social media Monday evening. "These allegations are very serious and credible. Graham Platner should drop out from the race. I am withdrawing my endorsement."

The blistering statement comes as Khanna, a far-left populist with likely presidential ambitions, had embraced Platner's insurgent Senate campaign for months amid a patchwork of controversies.

Khanna personally campaigned with the Maine Senate hopeful in June shortly before Platner won the Democratic primary nomination. The campaign stop came just one day after Lyndsey Fifield, a former Platner girlfriend, accused Platner of abuse — an allegation first reported by The New York Times that Platner has fiercely denied.

By that point, Platner was also facing scrutiny for sending sexually explicit messages to at least half a dozen women while married, making a plethora of offensive online statements over the period of a decade and getting a Nazi-linked tattoo that he wore for most of his adult life.

Khanna previously appeared to dismiss the severity of Fifield’s account alongside many Democratic lawmakers, who seized on her background in Republican politics. He also argued that Platner, a combat veteran who has struggled with PTSD, had overcome a dark past and was deserving of redemption.

"Here you have a case of someone who had a dark chapter in his life, was in toxic relationships, was ashamed about it, who served this country, and the Maine voters are saying, ‘Look, let’s give him some grace, and his focus is stopping these wars, and it’s getting national health insurance, and it’s taking on economic inequality," Khanna told CBS News in an interview.

And Khanna told Fox News’ Martha MacCallum in June that he asked Platner if there were any credible allegations of sexual assault that had yet to be revealed. He said Platner denied it.

"I made it clear that, for me, is a red line," the California lawmaker said. "And he said, no, there is not."

"Now, obviously, he had texts that were allegedly consensual, and while he was married, And that's a matter for him and his wife. And his wife came out and said that she forgave him. And so that is a different matter for me than abuse or assault or what people did in the Epstein class. It's a very different matter."

Khanna was not the only prominent Platner supporter to disavow the Senate hopeful following Monday's rape allegation.

Sen. Ruben Gallego, D-Ariz., rescinded his endorsement Monday evening, but stopped short of calling on Platner to exit the race.

Gallego, a former ally of disgraced ex-Rep. Eric Swalwell, D-Calif., has faced scrutiny over his past treatment of women. The Senate Ethics Committee recently dismissed a complaint brought by Rep. Anna Paulina Luna, R-Fla., in a bipartisan manner.

Far-left Twitch streamer Hasan Piker, who has championed socialist candidates across the country, also distanced himself from Platner on Monday.

"This is beyond red flags. This is irredeemable ," Piker said during his livestream.
