The popular video app stopped working shortly before a federal law barring U.S. companies from hosting or distributing TikTok was set to take effect on Sunday.

TikTok is set to be blocked in the U.S. after the Supreme Court upheld a law that effectively bans the app. TikTok, a Chinese-owned social media platform, has drawn scrutiny from lawmakers for its national security risks and its ties to China. Sapna Maheshwari, a business reporter for The New York Times, examines the security concerns and the reactions to the news.

The Chinese-owned company said it would cut off its services unless the U.S. assures Apple, Google and other companies that they would not be punished for hosting and distributing TikTok.

Ahead of a Supreme Court ruling, they are mocking U.S. national security concerns about the Chinese-owned app.

In 2020, he moved to ban the Chinese-owned app. Now, he is opposing the Biden administration’s effort to do just that.

An “international cybercriminal group” harvested the personal data of potentially hundreds of thousands of people from the state’s social services and health insurance systems, officials said.

The messaging app’s popularity has soared during the war with Russia, leading Ukrainian officials to increasingly weigh Telegram’s upsides against its security risks.

The law will ban the video app in the United States by Jan. 19 if its owner, ByteDance, does not sell it to a non-Chinese company.
