Ken Griffin has sharply criticized a viral video released by Zohran Mamdani, calling it a "personal attack" after the mayor highlighted Griffin's luxury penthouse while promoting a new tax proposal.
The dispute began when Mamdani posted a video on April 15 announcing a planned pied-à-terre tax. The policy would place an annual fee on high-value properties—especially those owned by people who do not live full-time in New York City.
