There's no telling yet if Trump's plan can set up a better version of Project Texas or convince China to sign off on a TikTok sale. Analysts have suggested that China may agree to a TikTok sale if Trump backs down on tariff threats.

"There's no legal basis for any kind of 'extension'" to keep the popular social media app running, warned GOP Sens. Tom Cotton and Pete Ricketts on Sunday.

TikTok owner ByteDance is reportedly still searching for non-sale options to stay in the US after the Supreme Court upheld a national security law requiring that TikTok's US operations either be shut down or sold to a non-foreign adversary.

US President Donald Trump on Tuesday said he would be supportive of the world's richest man and his close aide, Elon Musk, buying TikTok "if he wanted to". Trump was asked if he would be open to the billionaire founder of Tesla buying the short-video platform facing a nationwide ban in the US after the Supreme Court last week upheld a law requiring TikTok to sever ties with its Chinese parent ByteDance.

The Trump administration is denying it, but Trump previously said he'd like to see the software company take it over.
