The popular social video app will be banned in the U.S. in 45 days if it's not sold.
President Donald Trump issued an executive order on Thursday evening barring transactions with ByteDance, forcing the Chinese tech firm to divest itself of its U.S. TikTok operations.
The order, which is scheduled to go into effect in 45 days, gives a strict timeline for ByteDance to sell the business. Microsoft said on Sunday that it was in conversations with the company about acquiring TikTok's operations in the U.S., Canada, Australia and New Zealand.
TikTok, which has more than 100 million users in the U.S., has drawn scrutiny because of its Chinese owner. The Trump administration has worried that, through ByteDance, the personal data of U.S. TikTok users could find its way into the hands of the Chinese government.
