President-elect Donald Trump, who favored a TikTok ban during his first administration, has since flip-flopped on the matter. Late last month, he urged the Supreme Court to intervene and forcibly delay implementation of Biden's ban to give him time to find a "political resolution." His inauguration is Jan. 20.

Trump's rhetoric on TikTok began to turn after he met in February with billionaire Jeff Yass, a Republican megadonor and a major investor in ByteDance who also owns a stake in the owner of Truth Social, Trump's social media company.
