Social media users are comparing a gesture made by Zohran Mamdani at an inauguration to a similar one by Elon Musk, with some labeling Mamdani's action a 'Nazi salute.' Critics drew parallels to Musk's 2025 rally gesture, which also faced similar accusations. However, others defended Mamdani's movement as an enthusiastic wave or raised fist for emphasis. X's AI assistant, Grok, suggested Mamdani's gesture was for solidarity and not a Nazi salute, noting similar past debates.
