New York City’s self-proclaimed “transparent” new mayor is facing pointed questions after reports say he conducted government business on an encrypted app designed to keep messages out of public view.
Quick Take
- Reports say NYC Mayor Zohran Mamdani used Signal on a personal phone to communicate with officials and advisers, including at least some government business.
- Because Signal can encrypt and auto-delete messages, watchdogs warn it can conflict with New York’s public-record and FOIL expectations for preserving official communications.
- Politico reported the practice based on three anonymous sources and also confirmed Mamdani’s Signal account was active.
- Mamdani’s office did not respond to media questions in the initial wave of coverage, leaving the record-keeping issue unresolved.
Signal reports collide with a “transparent government” campaign brand
Politico’s New York Playbook and a separate Politico report said Mayor Zohran Mamdani has continued using Signal after taking office, with communication tied to elected officials and political advisers and including discussion of official government business. The reporting emphasized the tension with Mamdani’s 2025 campaign message promising openness and accountability at City Hall. Politico said it verified that Mamdani’s Signal account was active and registered to his personal cell number.
Townhall and Newsmax amplified the Politico reporting as the story spread on March 3, focusing on how encryption and disappearing messages can frustrate transparency rules that depend on preserved records. The core factual dispute is not whether Signal exists or whether it is secure; it is whether senior public officials should use an app that can make public business effectively unreviewable. Mamdani’s team did not publicly clarify what categories of conversations were routed through Signal.
Why record retention matters under FOIL—and why encryption raises alarms
New York’s Freedom of Information Law is built on a basic principle: when public officials conduct public business, the public has a legal pathway to request records. First Amendment lawyer Norman Siegel, cited in coverage, argued that mayors should not use Signal because it can conceal how government works, especially when a mayor has campaigned on transparency. Another perspective cited in reporting stressed that leaders must ensure official communications are preserved in some form.
The reporting also underscores a practical reality: even if a conversation starts as political strategy, it can slide into operational decisions once the speaker is the mayor. That blurring line is what makes the record-keeping question so central. Politico’s account relies partly on anonymous sourcing, which limits what the public can independently verify about the specific messages. Still, Politico’s confirmation of an active account strengthens the baseline claim of ongoing use.
Precedent: NYC’s recent history of encrypted messaging and public distrust
The controversy lands in a city still sensitive to past leadership scandals and “off-the-books” communication practices. Coverage drew parallels to scrutiny surrounding former Mayor Eric Adams and the use of encrypted apps during an investigation that was later dismissed, illustrating how quickly private channels can become part of public controversy. A separate, earlier legal fight during the de Blasio years also reinforced that mayoral communications are not casual texts—they can become contested public records.
That history matters because it shapes what New Yorkers will accept as “normal” in a post-scandal environment. If City Hall defaults to apps that the public can’t meaningfully access, the public’s ability to evaluate decisions—budget choices, enforcement priorities, and policy tradeoffs—shrinks. For voters who are tired of elite institutions insulating themselves from accountability, the optics alone can be damaging, even before any court challenge is filed.
What happens next: legal exposure, policy fixes, and the politics of oversight
Politico reported no confirmed policy change or investigation as of March 3, leaving open questions about whether Mamdani will shift communications to official systems that preserve records. The reporting raised the prospect of FOIL litigation or new city guidance restricting encrypted apps for official business, especially if watchdog groups pursue clarity. At minimum, the episode tests whether Mamdani’s administration will match its public language about accountability with record-retention practices.
Zohran Mamdani Has Already Broken His Promise to Be Transparent

Former City Council Republican leader Joe Borelli, cited in coverage, offered a defense that public officials sometimes seek privacy after previous probes, and that not every conversation is illegal. That argument may resonate with Americans who distrust politicized investigations. But the constitutional and civic problem is straightforward: when government business moves to channels designed to disappear, citizens lose a key tool for oversight. The next concrete step is simple—clear rules, preserved records, and answers on what was discussed and how it’s being archived.
