Citadel CEO Ken Griffin responded to a viral Tax Day video from New York City Mayor Zohran Mamdani in which he was filmed outside of the billionaire’s penthouse promising to charge new taxes on the property of wealthy individuals.

The democratic socialist, whose city is facing a budget crisis, released a video on April 15 vowing to impose a new pied-à-terre tax on the non-primary residences of wealthy New Yorkers.

Mamdani is seen in the video on the street outside Griffin’s penthouse, which was purchased in 2019 for $238 million — marking the most expensive home sale in American history, according to areportfrom Fox Business.

“This is an annual fee on luxury properties worth more than $5 million, whose owners do not live full-time in the city,” Mamdani said in the video.

“Like for this penthouse, which hedge fund CEO Ken Griffin bought for $238 million,” he continued, calling out Griffin by name.

Griffin responded with remarks at an investment conference in Oslo, Norway, saying that he was disturbed by the “personal attack” and the possible security ramifications.

“Like, you were at the White House Correspondents’ Dinner on Saturday where they tried to assassinate the president,” he told attendees. “Not too far from where I live in New York is where they assassinated the CEO of UnitedHealthcare.”

“So I think the willingness of the mayor of New York to make this policy debate a personal attack just demonstrated a profound lack of judgment,” Griffin added.
