Did you even read the article you referenced? In the very first paragraph...Trump has stated that he wants the US government to buy at least 50% of TikTok, but preferably more.
"President-elect Donald Trump said he would revive TikTok access in the U.S. by executive order after he is sworn in on Monday, but said he wants the popular social media app to be at least half owned by U.S. investors."
Not the US government...
