Fact-check: “Mamdani and AOC laughed while the names of those murdered on 9/11 are read out loud at the memorial ceremony in NYC.”
Verdict: Partly True (60% confidence)
Video footage from the September 11, 2026 ceremony at Ground Zero shows Mamdani and Ocasio-Cortez briefly laughing and conversing during the period when victims' names were being read, and multiple contemporaneous reports corroborate this. But no audio of their exchange was captured, so what caused the laughter is undocumented — the claim implies they were laughing at or about the reading, which the available footage does not establish.
