Supreme Court upholds law that could ban TikTok, though its future remains uncertain
The Supreme Court unanimously upheld a law that could ban TikTok in the U.S. by this Sunday unless its Chinese owner sells it. The Court said TikTok's popularity made it a threat to national security. But the Biden administration said it won't implement the law, leaving it to the incoming Trump administration to decide on next steps. President-elect Trump said he spoke today with China's President Xi about TikTok. NBC News' Savannah Sellers and Laura Jarrett report.
