White House backs bill that could give it power to ban TikTok nationwide

The bill would allow commerce department to impose restrictions on technologies that pose a risk to national security

The White House said it backed legislation introduced on Tuesday by a dozen senators to give the administration new powers to ban Chinese-owned video app TikTok and other foreign-based technologies if they pose national security threats.

The endorsement boosts efforts by a number of lawmakers to ban the popular ByteDance-owned app, which is used by more than 100 million Americans.
