TikTok to be banned in the US from Sunday

TikTok is to be banned in the US from Sunday if it is not sold by its Chinese parent company, the Supreme Court has ruled.

However, President Joe Biden has said he will not enforce the ban for the few remaining hours he is in office, leaving it up to Donald Trump to decide what to do when he enters the White House on Monday.

After the Supreme Court ruling, where the judges voted 9-0 in favour of the ban, the White House released a statement saying TikTok should remain available to Americans.

"TikTok should remain available to Americans, but simply under American ownership or other ownership that addresses the national security concerns identified by Congress in developing this law," the White House said in a statement.

The US's top judges were deciding whether to overturn the ban after hearing appeals from TikTok creators and its lawyers.

US officials banned the app over concerns its parent company could give data on American citizens to the Chinese government. TikTok's owners Bytedance have repeatedly said they won't sell the social media platform.

President-elect Donald Trump also tried to get the ban delayed, so he could make a decision on it once he was in office.

However, the Supreme Court has decided to stick with the original ban.

Now, one day before President Trump returns to the White House, the social media app used by 170 million Americans will be banned.

What happens on Sunday?

On Sunday, a few things could happen, especially now President Biden has said he will not enforce the ban.

There could be a quick beheading, with TikTok itself as the executioner.

There are reports the company will pull the plug for US users. When they attempt to open the app, people will see a pop-up message directing them to a website with information about the ban, Reuters is reporting.

At a Supreme Court hearing last week, TikTok's lawyer said the app would "go dark" in the US if the ban came into force.

Although there are a lot of American TikTok users, more than 1.5 billion people use TikTok worldwide, so the company could well decide it can manage without its US influencers.

If Mr Trump decides to enforce the ban, there could be a slow, painful death for TikTok in the US, where companies including Apple and Google take it off their app stores.

That will mean no new users can download the app and there won't be any updates.

The app will slowly get clunkier and buggier and US creators will start to disappear.

Or, the president-elect will work out a way of stopping the ban coming into force.

Will Donald Trump save US TikTok?

Mr Trump gets into the White House the day after the ban begins.

He is now a big fan of TikTok with more than 14.8 million followers. He even credited the app with helping him win back the presidency.

He may try to undermine the ban, but he does not have the power to overturn it.

He could, however, say he won't enforce it, and promise app store hosts such as Apple and Google they will not be prosecuted if they keep the app on their platforms.

Whether those major companies will want to take the risk of ignoring a legal ban is up for debate, however.

After the Supreme Court's decision, Mr Trump said he would make a decision quickly on how to deal with TikTok but he "must have time to review the situation".
