MEMPHIS, Tenn. --- TikTok is now unavailable for some users in the United States after the Supreme Court upheld a law banning the app. Late Saturday evening, some U.S. users received a message saying TikTok was unavailable due to the law banning the app. The ban was set to go into effect on Sunday, January 19. Friday, the United States Supreme Court unanimously upheld a federal law banning the app unless its parent company, which is based in China, sold it. The Supreme Court's ruling asserted that TikTok's ties to China posed a national security risk. Many of TikTok's 170 million users have spoken out against the ban, claiming that the ban will negatively impact the livelihoods of millions. Chloe Joy Sexton, a Memphis baker and popular content creator on TikTok, was one of several creators who joined a lawsuit opposing the ban. Memphis baker, TikTok star part of lawsuit in front of U.S. Supreme Court Sexton, who is a former WREG producer, says the app majorly impacted the success of her company. “TikTok has done more for me than anything in my life,” Sexton told WREG. “The other apps simply don’t have this power. They never have.” Sexton had amassed a following of 2.4 million TikTok users. Saturday, the app's message to users referenced statements by President-elect Donald Trump that suggest that he will work to delay the ban. Trump had previously supported a ban on TikTok but has since stated he will "mostly likely" grant an extension that would allow TikTok to keep operating. With a US ban on TikTok hours away, Trump says he ‘most likely’ will grant an extension President Joe Biden signed the law in April 2024 after it was approved by majorities in Congress. However, in the days leading to Trump's inauguration, the Biden administration announced that it would leave the ban's implementation and enforcement to the incoming Trump administration.
