Zohran Mamdani, New York City mayor since January 2026, has met President Trump at the White House on at least two prior occasions—an initial session shortly after the 2025 election and an unannounced February 2026 visit focused on federal support for housing. Their discussions center on affordability initiatives, including potential funding for the Sunnyside Yard rail-yard redevelopment that could add thousands of units, alongside immigration enforcement and public safety. The most recent encounter took place on September 21, 2026, at Gracie Mansion during the UN General Assembly, where the leaders coordinated further talks between city and White House officials but did not schedule a return trip to Washington. No additional White House visits have been announced through late September, leaving resolution dependent on any short-notice travel or policy-driven meetings within the relevant time windows.
