Mayor-elect Zohran Mamdani has made a strategic staffing move that has raised conservative concerns, announcing the appointment of two key figures with ties to the former de Blasio administration: Jahmila Edwards, a DC 37 union official, and Cat Da Costa, a former de Blasio staffer. These selections, announced on December 17, 2025, aim to balance Mamdani’s progressive ideals with pragmatic, experienced governance, strengthening his administration’s capacity to deliver for working-class New Yorkers. However, the inclusion of de Blasio aides signals a potentially complex interplay between maintaining campaign promises and navigating the realities of New York City’s political framework.
Story Highlights
- Mamdani’s team adds key figures with ties to former Mayor Bill de Blasio.
- Jahmila Edwards from DC 37 union joins as intergovernmental relations chief.
- Cat Da Costa, a former de Blasio staffer, is named head of the Mayor’s Office of Appointments.
- These appointments follow a period of silence from Mamdani’s transition team.
Mamdani’s Strategic Staffing Choices
On December 17, 2025, at a Brooklyn press conference, Mayor-elect Zohran Mamdani announced the appointment of Jahmila Edwards as Director of Intergovernmental Affairs and Cat Da Costa as head of the Mayor’s Office of Appointments. Edwards, a former DC 37 union official, strengthens labor ties, while Da Costa brings continuity from the de Blasio administration. These appointments come after weeks of silence during the transition period, addressing concerns over staffing amid 70,000 job applications.
The appointments showcase Mamdani’s strategy to balance progressive ideals with pragmatic governance. By selecting individuals with deep-rooted connections to New York City’s political and labor landscape, Mamdani aims to fortify his administration’s capacity to deliver on promises for working-class New Yorkers. This deliberate choice underscores the critical role of experienced operators in navigating complex intergovernmental relations and talent acquisition.

Implications for New Yorkers
Mamdani’s staffing decisions have both immediate and long-term repercussions for New Yorkers. In the short term, filling key roles expedites the transition and policy rollout process. Long-term effects include the potential for enhanced collaboration with state and federal entities, driven by Edwards’ expertise in intergovernmental affairs. The pro-labor focus, bolstered by Edwards’ union background, promises to prioritize working-class interests, aligning with Mamdani’s campaign rhetoric.
However, the inclusion of former de Blasio aides, like Da Costa, may signal a shift towards moderation, potentially easing relations with Albany and Congress. This balance between progressive ideals and established governance frameworks reflects Mamdani’s nuanced approach to leadership, aiming to bridge the ambitions of his campaign with the realities of operating within New York City’s political framework.
Conservative Concerns
For conservatives, Mamdani’s appointment of individuals tied to the de Blasio era raises concerns about the direction of his administration. The connection to de Blasio, known for policies criticized by conservatives for their expansive nature, may suggest a continuation of similar approaches under Mamdani’s leadership. The focus on labor unions, while beneficial for working-class advocacy, might also signal potential challenges in balancing fiscal responsibility with ambitious social agendas.
The decision to bring in experienced yet politically aligned figures suggests a complex interplay between maintaining campaign promises and ensuring effective governance. Whether this strategy will yield positive outcomes for all New Yorkers, particularly those concerned about government overreach and fiscal prudence, remains a pivotal question for Mamdani’s nascent administration.
