Fact Check: "Bernie Sanders endorsed Zohran Mamdani in the New York City mayoral primary on June 24, 2023."

What We Know

The claim states that Senator Bernie Sanders endorsed Zohran Mamdani in the New York City mayoral primary on June 24, 2023. However, this assertion is inaccurate. According to multiple sources, including a report by The New York Times, Bernie Sanders officially endorsed Zohran Mamdani on June 17, 2025, not in 2023. This endorsement came as Mamdani was preparing for the upcoming mayoral primary scheduled for June 24, 2025. The primary is part of the electoral process to select the Democratic nominee for the mayoral election.

Analysis

The discrepancy in the claim arises from the incorrect date associated with the endorsement. The endorsement by Bernie Sanders is confirmed to have occurred on June 17, 2025, as reported by various credible news outlets, including CBS News and The Guardian. The sources consistently highlight that Mamdani was a candidate in the 2025 mayoral primary and that Sanders' endorsement was a significant boost for his campaign against other candidates, including former Governor Andrew Cuomo.

The claim's reliability is further undermined by the fact that the 2023 date does not correspond with any relevant electoral events or endorsements related to Mamdani. The 2025 New York City Democratic mayoral primary is the correct context for Sanders' endorsement, as noted in the Wikipedia entry for the 2025 New York City Democratic mayoral primary.

Conclusion

Verdict: False. The claim that Bernie Sanders endorsed Zohran Mamdani in the New York City mayoral primary on June 24, 2023, is incorrect. The endorsement took place on June 17, 2025, ahead of the primary scheduled for June 24, 2025. This misrepresentation of dates leads to confusion regarding the electoral timeline and the candidates involved.
