WASHINGTON, DC: New York City's Mayoral candidate Zohran Mamdani's campaign has faced allegations that it profited from millions of dollars in donations from George Soros-linked charities as part of an elaborate scheme that may have violated federal tax laws. 

Mamdani's team has often claimed that the socialist rose from obscurity to become NYC's mayoral candidate, thanks to an organic, grassroots movement, consisting of small donations and hundreds of young people with backpacks canvassing on his behalf.

George Soros' group says report is 'riddled with inaccuracies'

Conservative investigative website, White Collar Fraud, alleged in its report that a network of tax-exempt organizations connected to billionaire financier George Soros coordinated political and ground operations to support Mamdani in a scheme, involving laundering more than $40million in charitable donations through non-profits and redirecting them into political activity.

Meanwhile, Soros' group disputed the report's findings of improprieties and said it is "riddled with inaccuracies, false assumptions, and misinformation".

A spokesman for the Open Society Foundation, founded by Soros, told the Daily Mail, "The math isn’t the only thing that doesn’t add up. The grants it cited – many of which we were earmarked for specific projects and causes elsewhere around the country as we have disclosed – were made years before the mayoral race even began."

However, White Collar Fraud investigator Sam Antar told the outlet that the Soros-affiliated entities may have violated federal tax laws.

Moreover, Antar also filed 11 whistleblower complaints with the Internal Revenue Service as a result of his investigation. He assists the government in white-collar fraud investigations and has lectured on such crimes on college campuses and at the IRS.

Weeks after Mamdani won the Democratic primary for mayor, various wealthy interest groups have begun to mobilize against the 33-year-old state assemblyman.

He called what he uncovered 'the manufacturing process of a generational political machine that has weaponized the income tax code' and described Mamdani as "a product of that machine".

He added that he uncovered how Soros's tax-exempt organizations helped fund activities that "mimicked what looked like a grassroots campaign", including large-scale door-knocking efforts.

"The problem is they weren't campaigning for a general cause like women's rights. They were campaigning for a specific candidate. And that's the rub," Antar said.

Report claims all six organizations ultimately endorsed Zohran Mamdani

The chief accusation in Sam Antar's investigation is that major 501(c)(3) charities, which are entities barred from engaging in partisan politics, funneled millions of dollars to affiliated 501(c)(4) social-welfare groups that can legally conduct limited political work.

His forensic analysis, which includes receipts such as citations to IRS filings, campaign finance records, and internal reports, alleges that the same network of non-profits that publicly describe themselves as "partners" in various progressive causes filed federal forms denying any coordination.

Earlier this week, Mamdani launched a “Costs Saved” calculator that helps to show much money people will save due to his three core policy proposals of universal childcare, a rent freeze for rent-stabilized apartments, and free buses.

As per the report, this discrepancy suggests not clerical error but what it describes as "systematic fraud".

Antar also alleged that this practice effectively "launders" tax-deductible charitable contributions into campaign support. His report names the Open Society Foundation and five other groups linked to Soros.

According to the report, all six organizations ultimately endorsed Mamdani and deployed field operations supporting his campaign, turning "charitable" deductions into political endorsements for the mayoral candidate.

Antar also mentioned that the six groups formed a "coordinated ground army" to support Mamdani's campaign.

The report also mentioned that a combined total of more than 100,000 doors were knocked across New York City, and extensive volunteer mobilization.

Interestingly, Antar informed the Daily Mail that he thinks Mamdani is going to win the election and that his goal is not to stop him, but to expose the underlying structure that is behind his meteoric rise.

"I kind of concede the fact that he's going to win. What I want to do is go after the machine that produces candidates like him," he said.
