LONDON (AP) — TikTok is in the crosshairs of authorities in the U.S., where new legislation threatens a nationwide ban unless its China-based parent ByteDance divests. It would be the biggest blow yet to the popular video-sharing app, which has faced various restrictions around the world.
TikTok is already banned in a handful of countries and from government-issued devices in a number of others, due to official worries that the app poses privacy and cybersecurity concerns.
