The Supreme Court on Friday allowed a ban on TikTok to take effect. Last year, President Joe Biden signed a law that would ban the platform unless its Chinese parent-company, ByteDance, sold it. In handing down its ruling, the court rebuffed an effort by the platform, some of its users, numerous free-speech advocates, and President-elect Donald Trump to halt the ban from taking effect. The case pitted Congress’ national security concerns against the free speech rights of TikTok and its users.
