New York City Mayor Zohran Mamdani's inaugural ceremony has sparked controversy online, with some MAGA supporters claiming a hand gesture resembled a Nazi salute and comparing it to a similar controversy involving Elon Musk. Mamdani's supporters and others dismiss these claims as misleading and politically motivated, stating the gesture was an enthusiastic wave or emphasis during his speech. The mayor's office has not yet responded to the allegations, while social media users debate the gesture's intent and context.
