DSA Members Urge Campaigns to Ditch Platner Consultant Who Advised Mamdani

Members of the Democratic Socialists of America circulated a letter calling on candidates and elected officials to refuse to work with the consultants who handled Graham Platner’s campaign, according to screenshots of the letter shared with The Intercept. 

“We, the undersigned, call on DSA candidates and elected officials to no longer contract or work with Morris Katz or Fight Agency, his political consulting firm,” the letter reads. 

Katz is not a member of DSA.

The letter also noted consultants at the agency like Rebecca Katz, who is not related to Morris, were also behind the campaign of Sen. John Fetterman, D-Pa., and said they continued to advise him even after he made a hard-right turn after entering the Senate.

Two sources with knowledge of the letter confirmed its authenticity.

“Morris Katz is one of the chief parties responsible for the catastrophic campaign of scandal-ridden Maine Senate candidate Graham Platner,” the letter says. “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 letter circulated as pundits and observers pinned the failures of Platner’s campaign on Katz and others at Fight Agency, including Rebecca Katz. (A spokesperson for DSA’s national organization said they had not seen the letter. Neither Morris Katz nor Rebecca Katz immediately responded to requests for comment.)

The agency is also currently working with Michigan Democratic Senate candidate Abdul El-Sayed, who is not affiliated with DSA. The Democratic socialist group has reportedly shifted resources to Michigan, where DSA is backing congressional candidate Donavan McKinney.

Katz’s Timeline

In a statement posted to X on Thursday, Katz said, “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.” 

CNN said the Platner campaign first denied the allegation in response to questions after an interview with the accuser, Jenny Racicot, whose allegation was first reported by Politico. The DSA members’ letter disputed Katz’s account.

“According to reports, Katz and others on the campaign were aware of at least some of Platner’s disturbing history,” the letter reads. “Yet even as the scandals mounted, Katz continued to put the full weight of his consultancy behind Platner’s candidacy, foreclosing the possibility of replacing Platner with another candidate before the primary election. Katz also reportedly threatened a former Platner staffer for helping verify allegations and controversies surrounding the campaign.” 

The alleged threat, first reported by the Bangor Daily News, targeted a Platner campaign staffer who had publicized an earlier sexting scandal and later left the campaign over Platner’s controversial Reddit posts.

Progressive Defenders

Some Democrats and progressives have pushed back against the criticisms of Katz and Fight Agency, arguing that Democratic consultants who worked with candidates they knew faced credible allegations of sexual misconduct, like former New York Gov. Andrew Cuomo or former Rep. Eric Swalwell, D-Calif. — or even former President Joe Biden — did not face the same kind of blacklisting. 

“Did we go knives out for Eric Swalwell’s consultants?” said one progressive strategist who requested anonymity in order to speak freely.

Some of the moderate Democratic critics of Katz’s role in the Platner campaign worked for politicians with their own scandal-ridden histories.

“This is not a problem unique to the left,” the strategist said. “This comes down to holding candidates accountable, and I think it’s no surprise that the same consultants who have laundered even worse politicians through the Democratic Party are the loudest ones right now.”

“The political world is chock full of useless consultants. Nobody cares when they fuck up a race,” said another progressive strategist. “The knives are out for Morris and Fight, because they’re actually good at what they do.”

Fellow Traveler?

Fight Agency’s most notable work for a DSA candidate was creating ads for Zohran Mamdani’s successful run to become the mayor of New York City, a race where Katz served as a political adviser. Katz also worked on the campaign of state Assembly Member Claire Valdez, the DSA candidate who won a New York Democratic primary for a House seat last month.

In the wake of Platner’s downfall, the letter says, liberals and conservatives have tried to claim that Katz represents the left as a whole.

The letter said, “Katz is linked in the mind of the media and political class to NYC-DSA,” the local chapter that boosted winning, Mamdani-backed congressional primary candidates like Valdez and Darializa Avila Chevalier.

The letter noted that such claims were bad for DSA, its candidates, and its movement. 

“Men like Platner must not represent the American Left, and those like Katz who push such candidates should have no role in our movement.”

“Our movement must be both ethical and strategic,” it says. “Katz has not shown an ability to be either. Any movement for democratic socialism in this country must be rooted in feminism and the multiracial working class, not archaic ideas of what constitutes a ‘worker.’ Allowing Katz an outsized influence in our movement undermines these ideals.”
