A member of Zohran Mamdani’s mayoral transition and top fundraiser for his campaign once celebrated vile anti-NYPD chants and called for America to be “punished for its sins,” The Post has learned.
Jack Gross, a far-left activist with deep ties to the New York City Democratic Socialists of America, repeatedly espoused far-left ideologies online and even praised Karl Marx, the 19th-century revolutionary who helped found communism.
Gross, who helped raise more than $20,000 for the Mamdani campaign, wrote on social media in June 2020 that it was “beautiful” when New Yorkers yelled “NYPD suck my d–k” — a common refrain heard during the George Floyd protests that summer.
“I must admit I do believe America is a wicked nation that must be punished for its sins,” he wrote a few months later, before his account went dormant.
Gross repeatedly spoke out on social media against US Immigration and Customs Enforcement and praised efforts by some detainees to escape agents from the federal agency.
He also shared a passage from a book on “Karl Marx Day” celebrating the “Communist Manifesto” co-author.
His controversial past posts came to light after Gross, a Canada native, was named to the 20-member “economic development & workforce development” committee by the mayor-elect’s transition team last month.
Gross, an editor at the lefty digital publication, “Phenomenal World,” run by the Jain Family Institute, served as an intermediary for Mamdani’s mayoral campaign helping bring in over $21,000 from more than 600 separate donors, records show.
He’s not the only controversial or radical member of the Mamdani transition to be exposed.
Most recently, it emerged that an ex-con rapper, Mysonne Linen, was named to the “criminal legal system” committee, with his name being overlooked originally since it had been misspelled by Mamdani’s team.
It also incorrectly spelled the name of Black Nationalist Lumumba Bandele — a member of the Malcolm X Grassroots Movement with a history of praising infamous cop killers — when announcing he’d serve on the “community organizing” committee.
Gross did not respond to a request for comment Monday.
“These statements don’t reflect the views of the Mayor-elect or the transition,” said Mamdani spokesperson Dora Pekec.
