TikTok resumed operations in the U.S. hours after shutting down, following President-elect Trump’s pledge to delay enforcement of a law banning the app. Trump promised an executive order to secure TikTok’s future, allowing its 170 million U.S. users to regain access. ByteDance, TikTok’s parent company, is exploring solutions, including a joint venture with U.S. ownership. Despite relief, the app’s long-term future remains uncertain due to bipartisan national security concerns and challenges in resolving ownership issues.
