The directive came in the form of an email from the campaign’s general consul Dana Remus on Monday. The news was first reported by Bloomberg.
The Biden campaign does not have an official presence on the app.
In the email, the DNC security team wrote, “We continue to advise campaign staff to refrain from using TikTok on personal devices. If you are using TikTok for campaign work, we recommend using a separate phone and account.”
TikTok, which is owned by a Chinese company, has been downloaded more than 165 million times in the US.
TikTok has pushed back on those claims, calling them “unfounded.” To underscore its independence from China, TikTok has cited its recently hired American CEO, and said it has “never provided user data to the Chinese government, nor would we do so if asked.”
