The claim mentions historical examples (Robert Wagner in 1957, Abe Beame's granddaughter) that are cited in the web search results. While the sources confirm the existence of these historical events and figures, they do not provide a unified, independently corroborated narrative of 'previous mayors having done their duty' with ceremonial gestures across multiple distinct sources. The evidence is descriptive but lacks the necessary corroboration across independent organizations to reach 'corroborated' status.

The claim states that Mamdani 'pointedly, mulishly kept any mention of the king off his public schedule.' However, the web search results contain conflicting information: one source mentions the visit and another mentions the lack of a private meeting, but none definitively confirm that he *omitted* any mention from his entire public schedule. The evidence is suggestive but not independently confirmed across multiple sources detailing his full schedule.
