New York City Mayor Zohran Mamdani has come under fire for using the encrypted messaging app Signal to communicate with elected officials while conducting government business.
On the campaign trail, Mamdani repeatedly promised his administration would be transparent. Yet, a Politico report revealed that the mayor used Signal from a personal phone number to communicate with elected officials and political strategists. In at least one of these exchanges, he discussed official city business.
Three people with knowledge of the matter told POLITICO that as mayor Mamdani has used the encrypted messaging app to communicate with fellow elected officials and political advisers. In at least one instance, he’s discussed government business over the app, according to one of those people, who like the others, was granted anonymity to discuss the sensitive issue.
POLITICO independently confirmed that Mamdani’s Signal account, registered to his personal cell phone number, remains active.
Norman Siegel, a veteran First Amendment lawyer who previously helmed the New York Civil Liberties Union, said mayors should never use Signal to communicate with other government officials as a rule of thumb — and that there’s another particularly important reason why Mamdani himself should avoid the app.
“With our new mayor, so much of what he’s articulating is a breath of fresh air,” Siegel said. ”I would urge him to not engage in Signal or similar kinds of applications that basically are meant to hide information and prevent the public from knowing the inner workings of government.”
