Rudy Giuliani offered some brutal “advice” for Mayor-elect Zohran Mamdani Monday — telling his successor he should never take office as leader of the Big Apple.
“My advice to him is to step down and do something else,” Giuliani told The Post of the proud democratic socialist who he branded a “communist — right out of Karl Marx.”

Giuliani, a Republican former two-term mayor of the city, blasted Mamdani as ill-equipped for the job and claimed he was a “supporter of Muslim extremism” after the Democratic Party nominee rubbed elbows with controversial Imam Suraj Wahhaj, a radical who had once urged a gun-free “jihad” on the city.
“The imam he was with is a strong supporter of terrorism,” Giuliani said, referring to a picture taken during the campaign of Mamdani — who will be the city’s first Muslim mayor — smiling widely with Wahhaj.
“I’m not worried that he’s a Muslim. I’m worried that he supports Muslim extremism,” Giuliani said.

Giuliani, who was once considered “America’s mayor” for leading the city during and after the Sept. 11, 2001 World Trade Center terrorist attacks, later went on to be a Trump attorney.
He was pardoned by the Trump administration for his part in the alleged effort to overturn the 2020 presidential election that saw Democrat Joe Biden defeat Trump. Trump returned to office after the 2024 election.
“You think the federal government will give this guy a security clearance?” Giuliani said. “Zohran Mamdani is a serious security threat to the United States of America. He’s a communist and a sympathizer for Muslim terrorism.”

He blasted Mamdani’s critical views of Israel and its Prime Minister Benjamin Netanyahu as “antisemitic.”
“Israel seems like an obsession with him,” Giuliani claimed, noting Mamdani’s support of the boycott, divestment and sanctions movement against Israel.
“The BDS movement wants to wipe out the State of Israel. Mamdani is one of the best known antisemites in the country,” Giuliani railed.
Giuliani said his other advice to his incoming successor was to “love America.”
The mayor-elect had no immediate comment on Giuliani’s stunning condemnation.
