The comments came during Fetterman’s appearance on MSNBC’s *Morning Joe*, where he directly addressed Sanders’ earlier remarks that he held “no regrets” about backing Sheyman, calling the accusations “unsubstantiated political smears.” “I’m saying this directly to Senator Sanders: stop this now,” Fetterman told hosts during the live interview. “We can’t spend decades telling survivors we believe them, telling women their voices matter, that sexual assault isn’t something to sweep under the rug, then turn around and throw our full support behind a man with multiple credible rape accusations just because he checks every progressive policy box. That’s not progress. That’s hypocrisy, and it’s going to cost us the trust of voters, especially women and independent voters, come November.” Sheyman, who is running for Illinois’ 10th Congressional District seat, has repeatedly denied all allegations, and no criminal charges were ever filed in relation to the 2015 incident. Sanders’ office issued a formal response hours after Fetterman’s comments, repeating that the Senator stands by his endorsement, noting that Sheyman has spent his career fighting for working-class families, raising the minimum wage and expanding access to healthcare, and that the allegations had been reviewed by local independent media outlets and found to lack supporting evidence. The high-profile feud has laid bare the growing rift between the moderate and progressive wings of the Democratic Party just four months ahead of the 2024 general election, where the party is fighting to hold its narrow Senate majority and flip control of the House of Representatives. Recent Pew Research Center polling shows that 62% of independent voters say they would be less likely to support a party that endorses a candidate facing credible sexual assault allegations, a statistic Fetterman referenced as a core motivation for his public pushback. Multiple national women’s advocacy groups have declined to take a formal stance on the fight so far, issuing generic statements noting that “all survivors deserve to have their allegations taken seriously, regardless of the accused’s political affiliation or policy positions.”
