SAN JUAN, Puerto Rico — TaxMam is coming.

Mayor-elect Zoran Mamdani was seen mingling with state legislative leaders in Puerto Rico on Friday, where he was lauded as a “man of the hour.” Meanwhile, Democratic socialists criticized President Trump, who reiterated his commitment to combat “authoritarian” regimes.

During the annual SOMOS conference, House Speaker Carl Heastie and Senate Majority Leader Andrea Stewart-Cousins hosted a gathering, with Mamdani working closely with the lawmakers required to realize the goal of “taxing the rich.”

“We’ve faced significant opposition to reach this point, and some of it amounts to tens of millions of dollars,” the 34-year-old congressman quipped to a crowd of long-time Paul supporters.

“Time and again, we’ve shown that voters who once turned away from Democratic defectors can be won back if we truly respect and appreciate them,” he continued, seemingly critiquing Democrats for their struggles to connect with constituents.

Mamdani urged the audience to collaborate as “partners” to demonstrate to New Yorkers that Democrats can indeed foster genuine change, while also restoring trust in government, which he believes has been lost for quite some time.

“At this moment, we have a chance to tackle both the dictatorship in Washington, D.C., and the affordability crisis that’s impacting our city,” the Ugandan-born politician emphasized.

“I’m eager to collaborate with the remarkable leaders who have championed this cause in Albany, and to expand those efforts from New York City, ensuring that we deliver on our promises.”

Heastie introduced Mamdani, calling him a “man of the hour,” and joked that the mayor-elect learned valuable lessons from him. He also playfully mentioned that Mamdani was “really proud” of introducing influential Bronx council members to Prince’s music.

Heastie, a significant figure among New York’s Democrats, suggested that “the message of caring for people ultimately trumps, and I mean ‘trumps,’ any challenges,” later telling reporters that Congress would back Mamdani’s “tax the rich” agenda.

“We want to support his policies and promote a conversation about how the people of New York state can best act to support the next mayor’s initiatives,” he added.

Stewart-Cousins also highlighted Mamdani’s new partnership with Governor Kathy Hochul.

“We recognize that these crucial moments matter, and these moments are ours,” the longtime state senator stated.

“We understand the mission, but never have we witnessed such unity among our leading partners in both chambers, the governor, the attorney general, and, of course, New York City.”

The Democratic Socialist mayor-elect told the Post that the recent historic election reflected New Yorkers’ backing of his agenda to increase taxes on billionaires and large corporations.

“There’s an unparalleled excitement emerging, with a clear vision for launching an affordable agenda and securing the necessary funding,” he remarked early Friday at the Islamic Center Montehiedra, a mosque in San Juan.

“I think these two tax proposals are quite reasonable.”

Mamdani proposes a 2% income tax on New York City residents earning over $1 million annually and an increase in the corporate tax from 7.25% to 11.5%, aligning it with New Jersey.

He argues this would largely cover his extensive promises, including free childcare and free bus services.

However, he mentioned being flexible about how the $10 billion plan would be financed. “We’re open to any viable funding options,” he said.

Yet, Mamdani’s plan to have wealthy individuals contribute towards his proposals has faced pushback from former ally Gov. Kathy Hochul, who suggested it might drive affluent residents and businesses out of New York.

This divergence led to a somewhat awkward exchange where Mamdani’s supporters, including those from Somos, consistently urged her to “tax the rich.”

“The more you pressure me, the less I’m inclined to do what you ask,” Hochul cautioned a lively crowd outside the El Caribe Hilton on Thursday night.

Both Heastie and Stewart-Cousins have shown more receptivity to taxing the wealthy.

The council president clearly stated in September his intention to use his influence in Albany to push for higher taxes on the rich.

“Polls indicate strong support for billionaire taxes,” he shared at that time.

While Stewart-Cousins hasn’t explicitly endorsed Mamdani’s proposal, he and fellow state senators have included options for tax increases on the wealthy in a largely symbolic one-house budget.

Many Democrats in Albany are becoming increasingly vocal about their willingness to support Mamdani’s tax proposals.
