Here is what Justices Brett Kavanaugh, Amy Coney Barrett, Kentanji Brown Jackson and Chief Justice John Roberts said about TikTok's Chinese parent company.

Justices at the United States Supreme Court have signalled scepticism towards a challenge brought by the video-sharing platform TikTok, as it seeks to overturn a law that would force the app’s sale or ban it by January 19.

Congress, which passed the TikTok law with bipartisan support, says China’s influence over the platform poses a national security threat. The Department of Justice has raised concerns as well, including the potential collection of personal data from the app’s millions of American users and the potential “ covert manipulation ” of its content.
