A Washington-based watchdog group has filed a formal ethics complaint against New York City Mayor Zohran Mamdani, alleging he repeatedly used his official position and taxpayer-funded resources to endorse Democratic candidates, and now wants the city's ethics board to act.
The Foundation for Accountability and Civic Trust, known as FACT, sent the complaint to the city's Conflicts of Interest Board on Tuesday, identifying three separate instances since Mamdani took office in January in which the mayor allegedly turned official press conferences into campaign platforms. In each case, FACT says, Mamdani stood behind the seal of New York City and his staff posted transcripts of the events on the city's official website, blurring the line between governing and electioneering in ways the city's own ethics rules were designed to prevent.
The complaint cites a 2009 advisory opinion from the same Conflicts of Interest Board that warned city politicians against using public resources to endorse candidates. FACT argues Mamdani has violated that guidance at least three times in roughly seven months, the New York Post reported.
Mamdani's office did not return a request for comment.
FACT's complaint lays out a clear pattern. In February, Mamdani held a press conference on universal childcare and used the occasion to endorse Governor Kathy Hochul, the Democratic incumbent running for a second full term. He also penned an op-ed backing Hochul.
At the February event, Mamdani was direct about his intent. "I'm proud to endorse her," he told reporters, while standing at a podium bearing the city's official seal.
In April, Mamdani endorsed Lindsey Boylan, best known as the first woman to publicly accuse former Governor Andrew Cuomo of harassment, for a City Council seat. Boylan's bid ultimately failed, but Mamdani used another official press conference to make his pitch. The ethics complaint isn't just about a stray remark at the end of an unrelated event. It centers on Mamdani weaving campaign endorsements into the fabric of official city business, with city staff posting full transcripts to a government website.
At the April event, Mamdani framed his endorsement as a matter of personal conviction:
"The decision to endorse Lindsey is one that comes more from having seen her bravery and her courage in standing up over the years. Early voting will continue through the 26th. And it's something that I'm glad to join my name to [support her]."
Then came June. At a press conference billed as an extreme-heat and worker-protection announcement, Mamdani endorsed eight Democratic primary candidates by name, five for state legislative seats and three others. He rattled off their names from the podium.
"I am looking forward to New Yorkers hearing about Claire, Darializa [and] Brad; [and] when it comes to the state legislator, Aber Kawas, Eli Northrup, Illapa Sairitupac, Samantha Kattan [and] Brian Romero," Mamdani said. "These are all candidates that I'm very excited about."
Eight endorsements in one go, delivered from behind the city seal at a taxpayer-funded event about heat safety. That is the conduct FACT wants investigated.
Kendra Arnold, FACT's executive director, framed the complaint in terms any voter can follow. The issue isn't whether a mayor can have political opinions. It's whether he can use the machinery of city government, the seal, the podium, the website, the staff time, to promote one party's candidates.
"Separating official activities from political ones is the foundation of sound ethics laws and imperative to maintain the public's trust in government."
Arnold went further, arguing that what Mamdani did amounts to putting a thumb on the scale with public money.
"The use of public resources to influence the political process gives a clear and unfair advantage to the individual or party in power."
The complaint itself opens with a blunt request: "We draft today to request you investigate Mayor Zohran Mamdani for using his official position and public resources for political activity." FACT is urging the board to impose penalties.
This is not the first time Mamdani has drawn scrutiny over ethics questions. The mayor accepted free World Cup tickets while insisting no ethics rules were broken, a claim that raised eyebrows among good-government advocates.
The Conflicts of Interest Board has shown it is willing to act against sitting mayors. In February, the board fined former Mayor Eric Adams $4,000 after his staffers placed multicolored whistles on reporters' chairs during a press conference the previous year, a stunt widely seen as a jab at the harassment accusations against former Governor Cuomo. If the board considered whistles on chairs a violation worth punishing, FACT's complaint raises an obvious question: what about a mayor who turned three official events into endorsement rallies for his party's candidates?
Arnold made the stakes explicit:
"Allowing this conduct to go unchecked and unpunished is a threat to the democratic process."
The board has not publicly indicated whether it will open an investigation or acknowledged receipt of the complaint.
The endorsement complaint lands on top of a pile of controversies that have dogged Mamdani since he took office. His housing adviser was found to owe $108,000 in unpaid rent and faced eviction as a squatter, an awkward look for any mayor, and an especially damaging one for a mayor who built his political brand on tenant advocacy.
Separately, Fox News reported that Mamdani himself has faced questions about his own rent-stabilized apartment in Astoria, Queens, where he pays roughly $2,300 a month, about $700 below the average market rate for a comparable unit. An economist from the American Institute for Economic Research filed a separate ethics complaint with the New York State Commission on Ethics and Lobbying in Government over the arrangement. Jason Sorens, the economist who filed that complaint, said he found it "implausible that while working as a Tenant Advocate, he would not know that his own apartment was rent stabilized." Mamdani has claimed he moved in when he earned only $47,000 a year and did not realize the unit was rent-stabilized.
The mayor's administration also exposed the names and addresses of nearly a million New Yorkers through a botched pied-à-terre tax list, including some of his own supporters.
And the controversies extend beyond policy. Families of 9/11 victims petitioned to bar Mamdani from Ground Zero's 25th anniversary ceremony, a public rebuke that underscored the depth of distrust the mayor has created in barely half a year.
FACT's complaint rests on a straightforward principle: when a mayor stands behind the city seal, speaks at an official event staffed by city employees, and has the transcript posted on a government website, that is a city event, not a campaign rally. The 2009 advisory opinion from the Conflicts of Interest Board said as much. Mamdani, according to the complaint, did it three times anyway.
The official @NYCMayor account on X promoted both the February childcare event and the June heat-wave press conference, linking to city resources. The February post, dated February 8, 2026, announced a "new request for information for 2-K and 3-K providers" and called it "the first step toward universal childcare." The June post, dated June 22, 2026, linked to the heat-wave and worker-protection announcement. Neither post mentioned the endorsements that took place at those events, but the transcripts the city published did.
That gap between what the city promoted and what the mayor actually did at those events is precisely what FACT wants the ethics board to examine.
When a mayor can't tell the difference between governing and campaigning, or simply doesn't care to, taxpayers are the ones left holding the tab.
