In one of his first acts as Mayor following his inauguration on Thursday, Mamdani issued an executive order that revoked all executive orders issued by his predecessor on or after September 24th, 2024, the day of Mayor Adams’ indictment. This action cancelled nine executive orders, which included multiple actions related to antisemitism and the Boycott, Divestment, Sanctions (BDS) movement, permission of immigration officers on Rikers Island, and a ban on horse-drawn carriages.
Mayor Mamdani has announced numerous appointments to his administration, including key appointments such as Dina Levy, Senior Vice President of Single Family and Community Development at New York’s Division of Homes and Community Renewal, as Commissioner of the Department of Housing Preservation & Development, Leila Bozorg, Adams’ Executive Director of Housing, as the Deputy Mayor for Housing and Planning, and Julie Su, a former federal Acting Labor Secretary, as the City’s first ever Deputy Mayor for Economic Justice. Other significant appointments include Helen Arteaga, CEO of NYC Health + Hospitals/Elmhurst, as Deputy Mayor for Health and Human Services, and Julia Kerson, an infrastructure adviser to Gov. Kathy Hochul and former Deputy of Operations under Mayor DeBlasio, as Deputy Mayor for Operations. He has also tapped New York City Comptroller Brad Lander’s Climate Chief, Louise Yeung, as Chief Climate Officer, former head of the Legal Aid Society, Steven Banks, as Corporation Counsel, and Ramzi Kassem, a former senior adviser in the Biden White House on immigration, as Chief Counsel. In his first act as Mayor, Mamdani named Mike Flynn as Commissioner of the Department of Transportation. See complete list of appointments here.
