In a major development in the race for New York City mayor, News 12 has learned that Zohran Mamdani will receive one of his most significant endorsements yet since winning the Democratic primary in June.

Sources confirm that the Bronx Democratic Party — including Borough President Vanessa Gibson and State Sen. Jamaal Bailey — will announce its support for Mamdani’s candidacy later this morning. They will be joined by seven other local lawmakers.

Mamdani has already earned support from several major unions that previously backed his opponent, Andrew Cuomo.

Stay tuned to News 12 for full coverage of the announcement and reactions from Mamdani’s challengers later today.
