TikTok, the widely popular video-sharing app, faces an uncertain future after President Trump signed an executive order that would restrict transactions…

Lawyers for the video-sharing app are likely to say the executive order was unconstitutional, arguing the company was not informed, as is standard, and the national-security concerns are baseless.

The president also issued an executive order aimed at cutting ties between the U.S. and the owner of the popular Chinese communications and social media app WeChat.
