Mayor-elect Zohran Mamdani revealed several top-level hires for his administration on Wednesday morning in Brooklyn as his team looks to address huge budget deficits as it enters office.

The transition announcement took place at Brooklyn Public Library in Greenpoint.

Mamdani announced that Jahmila Edwards will be the head of the Mayor’s Office of Intergovernmental Relations and will serve as his liaison to city and state government as he attempts to build support around his aggressive agenda.

Edwards is currently associate director of DC-37, one of the city’s largest unions and key supporters of the mayor-elect in both the primary and the general election.

Edwards previously worked at the city’s Education Department, including as executive director for the agency’s Intergovernmental Affairs Office.

“It is an honor to welcome Jahmila Edwards into this administration and to have her spearhead the work of partnership and collaboration that is critical to delivering the affordability agenda,” Mamdani said.

Mamdani is also announced Catherine Almonte Da Costa as Director of Appointments, another person from the de Blasio administration.

The role marks a return for Da Costa to New York City government, and to the Office of Appointments, where she began her career over a decade ago.

The Mamdani administration is fielding more than 70,000 applications from people who want to work in their government, and part of her responsibilities will be sorting through that.

“It is a privilege to serve the Mayor-elect’s Administration and be tasked with recruiting the talent that will be central to realizing the affordability agenda,” Da Costa said. “A Mayor’s strength lies in his team and we are committed to appointing a team defined by experience, competence, and dedication to the needs of working New Yorkers.”

Another pending announcement is expected in the coming days for Mamdani’s pick for director of the Mayor’s Office of Management and Budget.

“New Yorkers have entrusted us with a responsibility,” Mamdani said.”They voted for an administration that will work every day to make our city affordable and safe, to make the work of government efficient and excellent.”

However, delivering on that promise will be a challenge.

A study, by Comptroller Brad Lander, projects a $2.18 billion budget shortfall, possibly increasing to more than $13 billion by 2029 due to under budgeting of costs and sluggish economic growth.

President Donald Trump is expected to cut federal funding dramatically.Contract talks are looming for the Police Benevolent Association and DC-37, and that does not include money for Mamdani’s signature policy goals: free buses and universal childcare.

Mamdani insisted there are no plans to backtrack on any of his promises.

“It is critically important in our politics that we not only protect New Yorkers from cuts that are being proposed, whether at the federal level or here-with the prospect of these kinds of deficits-but also have a vision that goes beyond what we have today,” he said. “And doing these two things in tandem, it is going to be difficult, but it is necessary.”

Andrew Rein of the Citizens Budget Commission says it’s difficult, but not impossible.

“He needs to comb through city government,” he said. “What programs aren’t delivering for New Yorkers? Let’s shrink them or get rid of them. What is not doing enough? Get rid of it. Work with the unions. If we have a more efficient government, will have better services and help free up the money to close the budget gap and make progress, which he needs to do.”
