NYC Mayor Zohran Mamdani: Housing Tax Fights, Rent Battles and Early Clashes

Billionaire Bill Ackman called New York City Mayor Zohran Mamdani's policies disastrous for New York in a podcast interview this week. Billionaire Bill Ackman called out New York City Mayor Zohran Mamdani on Monday and labeled his policies a disaster for New York City. "Money Rehab" host Nicole Lapin asked Ackman if he was bullish or bearish on the socialist mayor. "I'm not a fan," he responded. "He's very smart, very charismatic, very good at politics, but I think the decisions he's making are very bad for New York." When asked if he'd consider running for mayor, Ackman said, "I would say possibly, but I think I could achieve a lot more by helping a very talented person do that job." Ackman brought up Mamdani's video detailing a proposed tax on second homes worth more than $5 million. He filmed the video outside hedge fund CEO Ken Griffin's apartmen
