Adams Ally Moves Quickly From City Hall to Lucrative Real Estate Work

As New York State was greenlighting up to three new casinos for the New York City area, gambling companies, breathless with excitement, descended on the mayor’s chief of staff.

Las Vegas Sands’s chief executive, Robert Goldstein, hosted Mr. Carone at his Upper East Side pied-à-terre, as The New York Times reported last year. And city lobbying records show Mr. Carone held meetings with the New York Mets owner, Steven A. Cohen, who wants to put a Hard Rock casino next to Citi Field, and Jeff Blau, the chief executive for Related Companies, the Hudson Yards developer looking to build a casino on the Far West Side of Manhattan.

Now, Mr. Carone is working for their competitor, SL Green, a hire first reported by Politico. A spokesman for the SL Green Caesars bid released a statement from Mr. Carone indicating that he would be helping to “create a diversified community engagement hiring plan as part of the proposal for a Times Square gaming destination,” and would not be lobbying on its behalf.

The spokesman said the company was “very excited to be working with Frank to ensure that Caesars Palace Times Square maximizes job opportunities for underrepresented communities across all five boroughs of New York City.”

A former Brooklyn Democratic Party lawyer and apparatchik with offices in Downtown Brooklyn, Mr. Carone used his year at City Hall to gain significant cachet. He now serves as the mayor’s designee on the board of the Museum of Modern Art, alongside billionaires like Ronald S. Lauder and Leon Black.

He held meetings with the likes of the JPMorgan Chase chief executive, Jamie Dimon; the Goldman Sachs chief executive, David Solomon; and the chief executive of Northwell Health, Michael Dowling, according to Mr. Carone’s schedules, which were released via a Freedom of Information Law request. Mr. Carone is now consulting for Northwell Health, according to Politico.

He has his eyes on a loftier perch — metaphorically and practically. His firm is planning to sign a lease at 724 Fifth Avenue, a building across from Trump Tower that is home to Prada’s flagship store, according to a person familiar with his plans. Mr. Carone had told Politico that he planned to occupy an entire floor at another building at 745 Fifth Avenue overlooking Central Park, but those plans fell through.
