Former FDNY Commissioner Robert Tucker, who quit when Zohran Mamdani won the mayoral election, broke his silence on his departure — saying he was turned off by the socialist’s campaign from the start.

Tucker, a Jewish philanthropist and businessman who was reportedly turned off by the mayor-elect’s anti-Israeli ramblings during the campaign, made his first comments over the bombshell decision during an interview with “CBS Mornings” host Tony Dokoupil set to air this week.

“What was the moment when you realized this mayor-elect, if elected, is incompatible with me, myself, my personal beliefs,” Dokoupil asked Tucker during an excerpt of the interview released Wednesday.

“I think the whole campaign really reflected that for me,” the outgoing commissioner replied.

Tucker cited his religion as a factor in his decision, and said Mamdani has some work to do if he hopes to win over the Big Apple’s rank and file first responders, the outlet said.

Tucker submitted his resignation to Mayor Eric Adams just hours after Mamdani, a Muslim state lawmaker from Queens, trounced former Gov. Andrew Cuomo in the Nov. 4 mayoral election.

The controversial mayor-elect has raised fears in the five boroughs over his democratic socialist agenda and has worried many in the Jewish community over his anti-Israel rhetoric.

Tucker will officially resign on Dec. 19, after serving just over a year in the post.

He is expected to return to the private security firm, T&M USA, a New York City-based company with connections to Israel which he headed before taking on the FDNY position.

Mamdani has often been critical of Israel and Prime Minister Benjamin Netanyahu over the Jewish state’s counteroffensive in Gaza following the sneak terror attack by Hamas on Oct. 7, 2023.

Tucker and the firm faced some controversy when Adams nominated him for the post, when it surfaced that one of T&M’s billionaire clients allegedly admitted to working with Chinese intelligence in the past.
