'TikTok is back': Trump teases future of social media app

President-elect Trump declared that TikTok is returning to the U.S. market, after its brief ban, during a pre-inauguration rally on Sunday under a new arrangement. 

This time, he told his supporters who gathered in Washington that he was aiming to create a deal in which the U.S. would have 50% ownership of the popular app’s operations. 

On Friday, the U.S. Supreme Court upheld the bipartisan law passed last year banning TikTok unless its Chinese-owned company ByteDance sells it by Sunday, citing national security risks because of its ties to China's communist government. The decision followed months of negotiations regarding national security concerns related to the app’s Chinese ownership.
