The popular social media app TikTok is accessible again in the United States after Trump vowed to issue an executive order to delay a ban on the app, which is used by 170 million people in the United States. The app became briefly inaccessible in the U.S. over the weekend after the Supreme Court unanimously upheld a federal law to ban TikTok starting January 19 unless its Chinese parent company ByteDance sold it to a U.S. buyer. Trump has proposed that the U.S. government or a U.S. firm take a 50% stake in the company. TikTok chief executive Shou Zi Chew is scheduled to attend Trump’s inauguration today.
