TikTok could go dark in the United States on Sunday after the Supreme Court upheld a ban on the Chinese-owned social media platform — but it could be back as early as Monday. President-elect Donald Trump said he will “most likely” delay a ban on TikTok for 90 days after he takes office on Monday but noted he has not made a final decision in a phone interview with NBC News on Saturday.

“Our position on this has been clear: TikTok should continue to operate under American ownership. Given the timing of when it goes into effect over a holiday weekend a day before inauguration, it will be up to the next administration to implement,” read the statement.
