TikTok has to cease operating in the US on January 19, a day before the inauguration, if its Chinese owner, ByteDance, doesn't sell the app.

As a last resort, the platform is preparing for a total shutdown Sunday, the day a U.S. ban is set to go into effect if the Supreme Court doesn’t overrule it.

TikTok CEO Shou Zi Chew plans to attend President-elect Donald Trump's inauguration on Monday as the company confronts a new law with a looming deadline requiring it to sell to a non-Chinese firm or stop operating in the United States, according to a source with knowledge of the inauguration plans.

TikTok CEO Shou Zi Chew will be a guest of Donald Trump at his inauguration Monday as the popular app’s ban is set to go into effect, according to three people familiar with his plans.

TikTok CEO Shou Chew is expected to attend President Trump's inauguration, NBC News reports. Also expected to attend is Google CEO Sundar Pichai, according to a Trump transition official. The news of the guest additions comes days before TikTok's impending ban in the U.

Shou Chew intends to go, as the company and the president-elect’s advisers consider options to delay or stop a ban of the popular video app.
