Self-described socialist Zohran Mamdani made headlines last week when he was elected as mayor of America's largest city.

While Mamdani's success raised alarm among conservatives, one figure says New York's incoming mayor is even worse than his critics think.

Son of Hamas founder calls Mamdani "a Trojan horse"

According to Breitbart, that assessment was put forward on Saturday by Mosab Hassan Yousef, who is the son of Hamas co-founder Sheikh Hassan Yousef.

The younger Yousef has converted to Christianity and worked covertly with Israeli intelligence to undermine his father's terror group.

"How can somebody who’s pro-disorder, pro-chaos, be trusted with ruling one of the most advanced cities in the West?" Yousef asked during an interview with Breitbart.

"Now, here’s what’s more dangerous about Mamdani. Mamdani is only a Trojan horse," Yousef continued before highlighting the alliance between Marxists and Islamists.

Yousef predicts that Arab oil money will bail out New York

"Mamdani identifies as a socialist — communism rebranded — while embracing Islamist ideology. These twin ideologies represent catastrophic failures wherever they’ve been implemented," he declared.

"The fact that he uses the Muslim victim card is another angle that tells me a lot about this person — making up stories that never happened, promoting chaos rebranded as 'Intifada,'" Yousef pointed out.

"Look at the Islamic countries — they can build tall towers and grand skylines, but they can never recreate New York’s freedom or America’s spirit…. That’s what Mamdani's socialist model would destroy," he stressed.

"The only way he’s going to manage to implement his socialist policies is through mismanagement," Yousef predicted.

"The wealthy would bolt, he won’t be able to pay the city’s bills, and the city would drown in debt. The only rescue would be Arab oil money — the same way in London. This is how it plays out. This is their playbook," the former Israeli agent added.

Mamdani praised co-conspirator in the 1993 World Trade Center bombing

Breitbart pointed out how during his campaign, Mamdani met with Imam Siraj Wahhaj, describing him as "one of the nation’s foremost Muslim leaders."

Today at Masjid At-Taqwa, I had the pleasure of meeting with Imam Siraj Wahhaj, one of the nation’s foremost Muslim leaders and a pillar of the Bed-Stuy community for nearly half a century. I was also joined by CM @dr_yusefsalaam of Harlem. A beautiful Jummah. pic.twitter.com/4kcN4CGlUk

Wahhaj was named by the Department of Justice (DOJ) as an unindicted co-conspirator in the 1993 World Trade Center bombing.
