NEW YORK — Mayor Zohran Mamdani is expected to permit at least some city government employees and agencies to use TikTok, reversing a ban his predecessor enacted out of data security concerns.

Mamdani, whose prolific social media use became a hallmark of his successful 2025 mayoral campaign, was set to announce the reversal of the TikTok prohibition as early as Tuesday, according to two people with direct knowledge of the situation.

The people, who were granted anonymity to discuss the new policy, told POLITICO that Mamdani will make the ban’s rollback official in a TikTok video posted to the @nycmayor account, which has been inactive since 2023 when former Mayor Eric Adams banned the app from being used on city government devices.

Besides resurrecting the @nycmayor account, Mamdani is expected to allow at least some city government agencies to start operating on TikTok again, said one of the people.

The lifting of the city’s TikTok ban has not been reported previously.

Following in the footsteps of a number of other U.S. cities and states, Adams’ administration announced in August 2023 that TikTok would no longer be allowed on city government devices. At the time, U.S. officials were raising concern that TikTok’s parent company, ByteDance, was too closely tied to the Chinese government, opening the door to Beijing potentially gaining access to sensitive American user data.

President Donald Trump tried to ban TikTok outright in the U.S. in 2020 over the platform’s Chinese government ties. But after his second inauguration, Trump has shifted course and sought ways to let the app remain operational in the U.S.

In light of Trump’s change of heart, TikTok, which denies sharing data with the Chinese government, has taken steps to separate itself from Beijing.

Earlier this year, ByteDance announced it had spun out a new American entity to run TikTok in the U.S. However, cybersecurity experts say that new structure still raises data security concerns, as ByteDance retains an ownership stake.

Dozens of states continue to ban employees from using TikTok on their devices. That includes New York State, which enacted its ban in 2020.
