TikTok Challenges U.S. Divest-or-Ban Law Over Secret Briefings

(Bloomberg) — The Chinese owners of TikTok are trying to overturn a new U.S. law seeking to ban the app unless it is sold because it was passed by U.S. politicians after a series of briefings that have remained classified,

ByteDance Ltd. must lay out its reasons for bringing the lawsuit by June 20. One of its main arguments is that Congress never provided public proof of a national security threat to justify a ban that the Beijing-based company says would infringe the free-speech rights of TikTok’s 170 million U.S. users.
