As national security officials prepare to brief senators on Wednesday about threats posed by TikTok, lawmakers questioned whether a forced sale of the Chinese-owned social media platform could lead to a different kind of foreign ownership.

The closed-door briefing on Wednesday comes after the House passed a bill to push ByteDance to divest within six months or face being banned in the United States. Members of the Senate’s Intelligence Committee and the Commerce, Science, and Transportation Committee will have access to the briefing as the Senate considers how to proceed on the House-passed bill.
