John Catsimatidis, the CEO of grocery chain Gristedes, found fault with Mamdani’s plan, saying the business couldn't compete in the market if there are city-run supermarkets.

"If the city of New York is going socialist, I will definitely close, or sell, or move or franchise the Gristedes locations," Catsimatidis told FOX Business. He will also contemplate moving his corporate offices to New Jersey. Catsimatidis said that he won't make this decision after the primary election.
