What the pending application means for City Hall
Eight months into his term, Mayor Zohran Mamdani’s federal security-clearance application remains unresolved. The clearance is used to give mayors classified briefings on terrorism and other threats affecting New York City. Former officials told Gothamist that the delay could leave Mamdani without the fullest available account of a developing crisis. Mamdani said in January that he was applying, and City Hall has continued to describe the review as ongoing.
The city has a parallel channel for receiving federally classified information. NYPD Commissioner Jessica Tisch, First Deputy Mayor Dean Fuleihan, and Chief Counsel Ramzi Kassem have clearances, according to City Hall. During the March 2026 U.S. and Israeli strikes on Iran, City Hall said those officials received classified threat briefings while Mamdani’s application was still pending, as reported by City & State New York. Cleared aides cannot pass classified briefing content directly to a mayor who lacks authorization, so the arrangement does not give Mamdani the same direct access.
The timeline is unusual but difficult to read as a verdict
The delay is longer than the time reported for two recent mayors. A former city official told Gothamist that Eric Adams received his clearance within five months of taking office; a former Bloomberg official said Michael Bloomberg received his within four months. Christopher O’Leary, a former official who led the New York Joint Terrorism Task Force, described it as unusual for a mayor to approach a first full year without clearance, while cautioning that a longer investigation does not by itself show wrongdoing. Former Police Commissioner Ray Kelly said the process can take more than a year and said he did not regard Mamdani’s status as a problem; both assessments were reported by Gothamist.
The investigative process itself can involve extensive forms, interviews, checks with references and relatives, and questions about foreign travel. Sabrina Shroff, an attorney who has undergone the process, described those steps to Gothamist. The Government Accountability Office has separately reported that federal agencies’ clearance-timeliness data contain substantial reliability problems and that the broader process remains on its High-Risk List because of delays and information-technology challenges: GAO. Those findings make the elapsed time difficult to interpret on its own.
Why the application has become a political issue
The application has also drawn an explicit demand for denial. Eight Republican lawmakers led by Rep. Andy Biggs sent a November 2025 letter to the Department of Homeland Security citing Mamdani’s co-founding of a Students for Justice in Palestine chapter and his past protests of the NYPD. The lawmakers’ position appears in the letter summarized by Biggs’s office. A Homeland Security spokesperson referred questions to the FBI, which did not respond to a request for comment reported by Gothamist.
Former Mayor Bill de Blasio has argued that a mayor needs the best available information to protect New Yorkers and that denying Mamdani a clearance would disregard the voters’ decision, according to Gothamist. The debate has unfolded alongside criticism that President Donald Trump has used security-clearance decisions against political opponents, including New York Attorney General Letitia James and Manhattan District Attorney Alvin Bragg. Those political arguments do not establish that Mamdani’s application has been denied or that the delay resulted from political interference.
The unresolved question
For now, Mamdani remains dependent on a system in which cleared officials can receive sensitive information while he awaits a decision. Former Deputy Mayor Randy Mastro, who attended classified briefings with Adams, told Gothamist that direct mayoral participation is preferable. The mayor’s office has said the current arrangement has not prevented the city from responding to public-safety needs, but the federal government has not publicly resolved whether Mamdani will receive the clearance.
