Summary
New York City Mayor Zohran Mamdani released a one-minute promotional video on April 15, 2026, filmed outside billionaire Ken Griffin's $238 million penthouse on Central Park South to advocate for a newly proposed pied-à-terre tax. The video, which accumulated 52 million views on X, features Mamdani explaining that the tax is "specifically designed for the richest of the richest, those who store their wealth in New York City real estate but don't actually live here." The proposal targets luxury properties valued above $5 million that remain unoccupied, aligning with Mamdani's campaign platform to raise taxes on the wealthy and corporations to address the city's affordability crisis.
The video immediately provoked sharp criticism from both Griffin and prominent media figures. Griffin, CEO of hedge fund Citadel, characterized the recording outside his residence as "creepy and weird," describing it as an insensitive invasion of privacy. CNBC anchor Sara Eisen reinforced these concerns, labeling Mamdani's approach "weird, scary, and insanely stupid stuff." Citadel formally objected to what it characterized as an attempt to leverage Griffin's name and property to advance political objectives. The backlash extended to the broader business community, with Citadel hitting back and other business leaders expressing concern about the mayor's tactics.
Business leaders and policy advocates, including Kathy Wylde, a prominent liaison between City Hall and New York's corporate sector now working at the lobbying firm Invariant, raised security concerns about personalizing policy debates through such videos. Wylde specifically referenced the current political environment, citing last summer's fatal shooting at a Midtown building housing NFL offices and Blackstone, as well as the 2024 assassination of an insurance CEO, arguing that these incidents underscore real risks when elected officials target specific wealthy individuals. Wylde stated: "In the current political environment, you can't personalize policy issues without negative repercussions, as we saw with the UnitedHealthcare CEO."
Despite the criticism, Mamdani's video achieved its political objective. The pied-à-terre tax proposal gained traction following Governor Kathy Hochul's support for similar legislation, delivering the socialist mayor a significant policy victory aligned with his core campaign messaging. The controversy underscores the deepening tension between New York City's progressive leadership and the business establishment, with fundamental disagreements over both tax policy and the appropriate boundaries of political rhetoric in an era of heightened security concerns.
