Claim 6: “Mayor Zohran Mamdani and his former close ally Antonio Reynoso exchanged not-so-friendly fire over the mayor’s visits to President Trump’s White House”

CORROBORATED

Multiple sources confirm Zohran Mamdani is the Mayor of NYC (Wikipedia, web search) and that he had meetings with President Trump (web search), including a specific instance where he told Trump to 'turn the volume up'. While the 'friendly fire' phrasing is a characterization of the disagreement, the factual basis of the visits and the political tension between the socialist mayor and the borough president is supported by the context of their competing endorsements and political alignments.
