New York City Mayor Zohran Mamdani broke his silence on the Graham Platner debacle this week, declaring at a news conference that he will keep working with Morris Katz, the 27-year-old political consultant at the center of one of the most reckless candidate launches in recent memory. Platner, the Democratic Senate nominee in Maine, withdrew from the race after a rape accusation from an ex-girlfriend, a trove of deleted Reddit posts, allegations of emotional abuse of women, and the discovery of a Nazi-linked tattoo he acquired during military service.
Mamdani's loyalty to Katz comes despite a growing chorus within his own political coalition demanding the consultant be cut loose. The Democratic Socialists of America circulated a letter urging allies to blacklist Katz from future campaigns. Members of the broader Democratic apparatus have called for the same. And yet Mamdani, standing before reporters on Monday, offered a flat endorsement.
Fox News reported that Mamdani told the press:
"I will continue to work with Morris Katz, he remains a top advisor of mine."
His office did not respond to Fox News Digital's request for comment on Monday. That silence speaks volumes about the mayor's willingness, or unwillingness, to answer basic questions about the judgment of the people closest to him.
The Platner campaign's collapse did not happen because warning signs were hidden. It happened because warning signs were ignored. A source familiar with the early stages of the campaign told Fox News Digital that Katz and his consulting partner, Daniel Moraff, paid just over $6,000 for a three-day background check on Platner. Standard vetting for a Senate candidate usually takes weeks and costs tens of thousands of dollars.
The vetting team flagged concerns and made multiple requests to dig deeper into Platner's past. Katz and Moraff ignored them.
Moraff, described as a top strategist for the campaign, laughed when asked about his vetting process and admitted their firm missed controversial details. That casual attitude toward due diligence is not a minor oversight. It is the kind of institutional negligence that puts a party's credibility, and the voters it asks to trust it, at serious risk.
As Just The News detailed, Moraff ordered an expedited, cursory background check that failed to uncover the full scope of Platner's sexual misconduct history. Platner was accused by at least three women of emotionally abusive behavior and by two women of sexual assault, ultimately forcing him to suspend his campaign. Katz himself was quoted saying that within "five minutes of meeting with Platner," he was thinking the candidate could "help save the Democratic Party."
Five minutes of enthusiasm. Three days of vetting. And a Senate candidacy that imploded under the weight of allegations that even a modest investigation would have surfaced.
Katz's role did not end at recruitment. When the scandals began to surface, he moved to manage the fallout, and, according to reporting, to intimidate people who cooperated with the press. The Bangor Daily News obtained a message Katz sent to former Platner staffer Genevieve McDonald. In it, he warned her directly:
"Just want to be clear on where we are right now. If the story goes in its current iteration we'll communicate directly on the record, and by name, that Genevieve violated the personal trust of Amy and Graham and shared explicit falsehoods to sabotage the campaign."
That message reads less like a clarification and more like an attempt to silence a potential witness. The New York Post reported that Katz allegedly pressured McDonald to deny Platner's sexting scandal to the Wall Street Journal and to record herself doing so. When McDonald did not comply, the threat of public reputational damage followed.
This is the adviser Mamdani has chosen to keep. Not a consultant who made a bad bet on a flawed candidate and owned up to it, but one who, according to multiple reports, tried to shut down the people raising legitimate concerns.
After Platner announced his intention to suspend his candidacy, Katz posted on X that "as soon as the team became aware of the rape allegations against Graham Platner we advised he suspend his candidacy, and in the following days worked to wind down the campaign." He said he was "deeply disappointed." But a community note attached to his post pointed out that Platner's campaign had initially denied the rape allegation altogether.
The pattern is familiar: deny, deflect, then claim credit for doing the right thing once the situation becomes untenable. Democrats have scrambled to distance themselves from Platner, but Mamdani is walking in the opposite direction.
The Platner fiasco is not the only controversy trailing Katz. In 2020, he authored a puberty book marketed to "curious boys" aged 10 to 12. The book includes sections titled "Your New Penis" and "The Magic of Masturbation." On page 15, a footnote states that Katz planned to "use images of my penis" to show children how genitalia develop during puberty, but that publishers rejected the idea as "inappropriate."
When the footnote drew public attention in March, the backlash was swift. The National Republican Senatorial Committee issued a statement calling Katz's "musings about exposing himself to ten-year-olds" "absolutely disgusting." Chaya Raichik, who operates the conservative X account Libs of TikTok, posted: "Only a perverted freak would say that."
Katz later said the comment was a joke. Whether it was or not, the fact that a top political consultant to the mayor of America's largest city wrote, and published, such a footnote in a book aimed at children is the kind of detail that invites serious questions about judgment. Questions Mamdani apparently has no interest in answering.
Even the Democratic Socialists of America, not exactly a bastion of conservative accountability standards, concluded that Katz had to go. Their circulated letter was blunt:
"Morris Katz is one of the chief parties responsible for the catastrophic campaign of scandal-ridden Maine Senate candidate Graham Platner. Billed as a top adviser to the campaign, Katz helped recruit Platner and supercharged his candidacy with slick video production, friendly media placements and political connections."
The Washington Examiner noted that the DSA called on progressive campaigns to stop working with Katz, stating: "Men like Platner must not represent the American Left, and those like Katz who push such candidates should have no role in our movement."
When your own ideological allies are telling you to cut someone loose, and you refuse, you are making a deliberate choice. Mamdani is not standing by Katz out of ignorance. The facts are public. The letter is public. The threats to a former staffer are public. The $6,000 vetting shortcut is public. The puberty book footnote is public.
Katz helped engineer Mamdani's upset victory over Andrew Cuomo and Curtis Sliwa. That loyalty now appears to be the only currency that matters in Mamdani's political calculus, more than accountability, more than the safety of women who came forward with allegations against Platner, and more than the basic credibility of the office he holds.
This is hardly the first time Mamdani's inner circle has drawn scrutiny. His aides have confronted network executives over unfavorable coverage of allied candidates. His administration has generated controversy on the international stage as well, with the State Department shutting down a planned meeting between a Mamdani official and Iran's UN ambassador.
The Platner disaster was not a single mistake. It was a chain of failures, rushed vetting, ignored warnings, alleged intimidation of a whistleblower, and a candidate whose history of alleged sexual misconduct, controversial tattoo, and inflammatory online posts should have disqualified him long before primary night in Blue Hill, Maine, on June 9, 2026.
Every link in that chain runs through Morris Katz. And every link now runs back to Zohran Mamdani, who looked at the wreckage and said: keep him.
Mamdani's allies in the broader progressive movement have generated their own share of troubling headlines. But the mayor's refusal to distance himself from a consultant credibly accused of threatening a former staffer, cutting corners on vetting, and authoring disturbing content aimed at children sets a new standard, even for a political class that has made a habit of looking the other way.
Fox News contributor Jonathan Turley described the strategists involved as "unserious" and pointed to the severe implications of the failed vetting for Democratic Party credibility and the integrity of the election process. That assessment is generous. What happened in Maine was not a lack of seriousness. It was a lack of basic responsibility, and the man now running New York City just told the world he sees nothing wrong with it.
Voters deserve leaders who hold their own people accountable. Mamdani has made clear he is not that kind of leader.
