President Joe Biden and his team think that TikTok is a national security threat, but they also want to encourage the public to use it.

Biden’s campaign decided to join TikTok, which it boasted about on Sunday in a post on X. John Kirby, newly appointed as the White House’s national security communications adviser, said that “nothing’s changed about the national security concerns” about TikTok on government devices. Biden signed a ban on the app on government devices at the end of 2022.
