Joel Rubin, a former campaign official for Senator Bernie Sanders, has publicly criticised the Vermont senator, accusing him of backing what Rubin called some of the "most categorically antisemitic candidates" in a generation. The comments, made last week, add to a wider debate within Democratic circles about the party's association with figures on its left flank and how such alliances are perceived on issues relating to antisemitism.

The criticism comes from someone with direct past experience working on Sanders's campaign, lending it added weight as an inside critique rather than an outside political attack. Beyond Rubin's remarks, the available report does not detail which specific candidates or endorsements prompted the comments, nor has Sanders's office issued a public response noted in the article.
