A government watchdog has filed a formal ethics complaint accusing New York City Mayor Zohran Mamdani of repeatedly using his official position and taxpayer-funded resources to endorse Democratic candidates, a pattern that now spans at least three press conferences and may include the use of mayoral vehicles for campaign activity.
The Foundation for Accountability and Civic Trust, a Washington, D.C.-based nonprofit, sent a letter to the city's Conflicts of Interest Board on Tuesday urging an investigation into Mamdani. The complaint identifies three separate instances since January in which the mayor stood behind the official seal of New York City and used city press conferences to publicly endorse political candidates. Transcripts of those events were then posted on the city's official website, effectively turning municipal infrastructure into a megaphone for partisan endorsements, the New York Post reported.
The complaint is not an isolated accusation. It lands amid a growing list of ethics questions surrounding Mamdani's young administration, and it invokes a 2009 advisory opinion from the very same board, one that explicitly warned city officials against using public resources to endorse candidates.
Mamdani's office did not return a request for comment.
FACT's complaint lays out a timeline that starts almost immediately after Mamdani took office in January. In February, the mayor held a press conference on universal childcare and used the occasion to endorse Governor Kathy Hochul, the Democratic incumbent running for a second full four-year term.
"I'm proud to endorse her," Mamdani said at the event, standing behind the city seal. He also penned an op-ed backing Hochul around the same time.
In April, Mamdani endorsed Lindsey Boylan, the first woman to publicly accuse former Governor Andrew Cuomo of harassment, at another official press conference. Boylan was running in a City Council race that she ultimately lost.
Kendra Arnold, FACT's executive director, told the Post that the pattern represented a fundamental breach of public trust:
"Separating official activities from political ones is the foundation of sound ethics laws and imperative to maintain the public's trust in government."
The third alleged violation came on June 22, when Mamdani held a press conference billed as an extreme-heat and worker-protection announcement. During the event, he endorsed eight Democratic primary candidates by name, three running for unspecified offices and five for state legislative seats, including Aber Kawas, Eli Northrup, Illapa Sairitupac, Samantha Kattan, and Brian Romero.
Mamdani made no effort to separate the endorsements from the city business at hand. "I am looking forward to New Yorkers hearing about Claire, Darializa [and] Brad," he said, before rattling off the state legislative candidates. "These are all candidates that I'm very excited about."
Arnold framed the conduct in blunt terms:
"The use of public resources to influence the political process gives a clear and unfair advantage to the individual or party in power. Allowing this conduct to go unchecked and unpunished is a threat to the democratic process."
The FACT complaint is not the only ethics filing Mamdani faces. NYC Councilman Phil Wong separately filed a formal complaint with the same Conflicts of Interest Board alleging that Mamdani misused official mayoral vehicles and NYPD security to transport one of his endorsed candidates, Darializa Avila Chevalier, during the final stretch of her primary campaign. Video footage showed Mamdani's top political strategist, Morris Katz, escorting Chevalier into an unmarked black SUV that appeared to be part of the mayoral security detail, with an earpiece-wearing bodyguard present, the Washington Free Beacon reported.
Wong pointed to an even earlier incident: on May 1, Mamdani reportedly filmed a campaign video at Gracie Mansion, the official mayoral residence, to support another candidate, Claire Valdez.
"Taken together, those earlier incidents and the apparent use of mayoral NYPD resources to ferry Ms. Avila Chevalier between campaign stops suggests a troubling pattern of blurred lines between official City functions and campaign activity," Wong wrote in his complaint. He added that "New Yorkers deserve confidence that City resources are being used solely for public purposes and not to advance the interests of favored candidates or political allies."
Mamdani's administration has faced scrutiny on multiple fronts beyond the ethics complaints. His handpicked schools chancellor, Kamar Samuels, faces potential criminal charges over allegations involving questionable contracts, a scandal that reportedly blindsided the mayor's office.
FACT's complaint rests on a specific piece of city guidance: a 2009 advisory opinion from the Conflicts of Interest Board that warned New York City officials against using city resources to endorse candidates. The opinion was designed to draw a clear line between official duties and political activity, exactly the line Mamdani's critics say he has erased.
In all three instances cited in the complaint, Mamdani stood behind the official seal of New York City. His staff posted full transcripts of the press conferences, endorsements included, on the city's website, effectively embedding partisan political speech into the official municipal record.
The mayor has also drawn questions for dodging accountability on other controversies, including his handling of a Brooklyn Democrat who promoted antisemitic pamphlets.
FACT urged the Conflicts of Interest Board to "impose the proper penalties" on Mamdani. The complaint letter is publicly available as a PDF filing addressed to the board.
The ethics board has shown it is willing to act. In February, it fined Mamdani's predecessor, former Mayor Eric Adams, $4,000 after Adams staffers placed multicolored whistles on reporters' chairs during a press conference, a stunt meant to jab at the harassment accusations against Cuomo. That fine was imposed for conduct far less systematic than what FACT now alleges against Mamdani.
Adams's violation involved a single incident of political messaging embedded in an official event. Mamdani's complaint catalogs three separate press conferences across four months, involving endorsements of at least ten candidates, with official city resources, the seal, the venue, the transcripts, and potentially mayoral vehicles, used each time.
The broader pattern extends to policy reversals and controversial positions that have defined Mamdani's short tenure. He reversed a campaign pledge about arresting a foreign leader after taking office, and he has left the door open to cash reparations while deferring to a city commission rather than taking a clear position.
Whether the Conflicts of Interest Board will open a formal investigation remains to be seen. The board has not publicly acknowledged receipt of either the FACT complaint or Councilman Wong's filing.
When a mayor treats every city press conference as a campaign rally, the taxpayers footing the bill deserve more than silence from his office.
