The Supreme Court heard oral arguments from both sides on Jan. 10. During the more than two-hour session, justices peppered TikTok's head lawyer with questions about the app's ties to China and appeared generally unconvinced by TikTok's main argument, that the law violates the free speech rights of its millions of individual users in the U.S.

On Thursday, businessman Frank McCourt's internet advocacy group Project Liberty announced it had submitted a proposal to buy TikTok from ByteDance. Calling it, "The People's Bid for TikTok," the group said it would restructure the app to exist on an American-owned platform and prioritize users' digital safety, though it didn't disclose terms of its bid.
