U20 Summit Press Access — Mamdani Bars Reporters from Most Sessions, Undisclosed Site Tour

For the Sept 19-21 Urban 20 Summit — NYC's first time hosting the G20-city mayoral gathering — most Saturday sessions and the Sunday wastewater-treatment-plant tour were closed to press, and meeting locations for private mayoral discussions were not disclosed in advance. City Hall says summit conventions typically restrict press to opening/closing plenaries; right-leaning outlets and conservative commentators framed the arrangement as a "secretive global elite" gathering. No press-freedom groups have filed formal complaints as of the closing day.
