Morris Katz, the 27-year-old progressive operative credited with fueling Mayor Zohran Mamdani's rise, allegedly skipped months of rent on a $6,500-a-month Brooklyn apartment, then bounced a check when he finally tried to pay up.
Katz signed a six-month lease last November on a two-bedroom, three-bathroom duplex with a private roof deck atop a four-story building on Lorimer Street in Williamsburg. He was late on rent from the start. Building representatives hounded him for payments during the first three months. Then, the New York Post reported, he stopped paying entirely.
By the time his lease expired on April 30, Katz owed $14,000. He offered to settle the full balance, and the check bounced. His family eventually wired the funds to cover what he owed. Weeks later, in early June, his belongings and trash were finally cleared from the unit.
Felix Barbosa, the building's superintendent, did not hold back when a Post reporter found him hosing down the sidewalk outside the building on Thursday.
"It was one of those things to get the rent you had to pull out his f, king teeth. But then he came back and paid everything, $14,000. I don't know where the money came from."
Barbosa added that Katz left the apartment in disarray, with no effort to clean up after himself. Photos obtained by the Post showed a loaded bar cart, a junk-filled closet, random furniture, and a refrigerator packed with takeout boxes and wrapped-up leftovers.
Katz is not someone who grew up worrying about making rent. He was raised in a $5 million apartment. His father, David Bar Katz, is a screenwriter and television producer. His mother, Julie Merberg, is a children's book author. His godfather was the late actor Philip Seymour Hoffman. The Post described him as having rubbed elbows with big-time actors from a young age.
None of that privilege stopped him from stiffing a working landlord in Brooklyn for months.
Barbosa, who dealt with the situation firsthand, offered a blunt assessment.
"When you come from a rich family, you don't have your priorities in order."
He also alleged that Katz's debts extended beyond rent. "He owes Con Edison money. He owes the gas company money. He owes everyone money," Barbosa told the Post. He called Katz "not a bad guy" but said his priorities were "all f, ked up."
A spokesperson for The Fight Agency, the consulting group Katz co-founded, offered a different explanation. The spokesperson said that when it came time to settle the balance, Katz did not yet have a checkbook with his new bank, so he sent his family the funds to use theirs and paid the balance in full. The spokesperson also said Katz cleared out his remaining belongings when he returned from traveling for work.
Reached by the Post on Thursday, Katz tried to claim the super's comments were being taken out of context. But he did not dispute any of the underlying claims. He said only that he had stayed in "communication" with the landlord during the months he was not paying rent.
During the months Katz was allegedly dodging his landlord, he was not idle. He was advising multiple congressional candidates ahead of New York's June Democratic primaries, including Democratic Socialists of America candidates Darializa Avila Chevalier and Claire Valdez, as well as Brad Lander and Micah Lasher.
He was also working with Graham Platner, a Maine Senate hopeful whose campaign imploded after Platner faced a rape accusation. Katz allegedly threatened a whistleblowing ex-staffer connected to that campaign. The nature and status of that allegation remain unclear.
Barbosa summed up the pattern plainly: "He has too much on his plate that he can't handle, that's what happened with him."
Katz is not a peripheral figure in New York City's progressive political machine. He co-founded The Fight Agency, and the Post described him as the operative who fueled Mamdani's rise from a relatively unknown, backbench state lawmaker to the mayor's office. That makes his conduct toward a private landlord more than a personal embarrassment. It is a window into the culture around City Hall.
The Mamdani administration has made targeting landlords a central policy priority. Tenant advocate Cea Weaver, who has called for the seizing of private property, leads a key City Hall initiative aimed at landlords the administration considers bad actors. The Mayor's Office of Mass Engagement has prioritized getting tenants to attend board meetings to champion the administration's rent freeze on stabilized units.
That agenda has already drawn scrutiny. Mamdani spent taxpayer money on a tenant-organizing documentary starring an aide who publicly called for seizing private property.
His administration's pied-à-terre tax rollout has been equally contentious. A searchable database of second-home owners drew accusations that City Hall was publishing a hit list of property owners.
Roughly 17,000 New Yorkers received notices under the new tax, many facing a burden-of-proof nightmare to demonstrate they were not subject to the levy.
And the controversies extend beyond housing policy. Nearly 17,000 9/11 families and supporters petitioned to bar Mamdani from the 25th anniversary ceremony at Ground Zero.
No eviction proceeding or legal action against Katz has been reported. The $14,000 balance was ultimately paid, and Katz's spokesperson emphasized that fact. But the circumstances raise questions that neither Katz nor his spokesperson addressed.
Why did a 27-year-old from a wealthy family, earning consulting fees from multiple political campaigns, fail to pay $6,500 a month in rent for months on end? Why did his first attempt to settle the debt bounce? And why did the apartment sit full of his belongings and trash for more than a month after his lease expired?
Katz did not dispute the facts. He disputed the tone. That is not a rebuttal. It is a deflection.
The Mamdani orbit lectures landlords about greed and accountability while its own political architect could not be bothered to pay his rent on time, or clean up after himself on the way out. That gap between the sermon and the conduct is the whole story.
