President-elect Donald Trump is considering an executive order to prevent the TikTok app from being banned in the United States, according to a report by The Washington Post on Thursday, citing sources familiar with the matter.

The proposed order would delay the enforcement of a law requiring TikTok to either be banned or sold by January 19 for a period of 60 to 90 days. This would give Trump’s administration time to negotiate a sale or find an alternative solution. However, the legality of such an action is reportedly uncertain.

In parallel, the outgoing administration of President Joe Biden is exploring options to keep TikTok available in the US. NBC News reports that the White House is working on an approach to enforce the law in a way that would allow users to continue accessing the app once it takes effect on Sunday.

Earlier this week, The Information reported that TikTok was preparing to shut down for US users on January 19. In April 2024, Biden signed a law mandating that TikTok’s parent company, ByteDance, find an American owner for the app. If this condition isn’t met by January 19, the app faces a potential ban.

Trump has asked the U.S. Supreme Court to delay the implementation of the ban until after his inauguration on January 20, to allow time for resolution of the issue.

TikTok, which launched in 2018, is under investigation by US authorities over concerns that it may be sharing user data with the Chinese government or spreading propaganda, charges the app has consistently denied. TikTok has around 170 million users in the US.
