TikTok is getting closer to being kicked out of the US after the Senate approved a bill that would ban the platform unless its Chinese owner ByteDance sells the company.
The video sharing app has millions of users around the world, but faces growing questions over the security of users' data and its links to the government in Beijing.
The House of Representatives and Senate have now both passed legislation which, among other things, forces the platform's parent company to divest.
President Joe Biden has vowed to sign the ban into law.

Who wants to ban TikTok in the US and why?
Lawmakers from both major US parties have pressed for a law that bans TikTok unless ByteDance agrees to sell the app to a non-Chinese company.
They fear the Chinese government could force ByteDance to hand over data about TikTok's 170 million US users. TikTok insists it would not provide foreign user data to the Chinese government.
On 21 April, House lawmakers approved a $95bn (£76bn) foreign aid bill with funds for Ukraine, Israel and Taiwan that also clears the way for the forced sale of TikTok.
4월21일 하원의원들은 우크라이나, 이스레엘, 대만을 위한 950억 달러의 해외원조 법안을 승인했고 이 법안은 틱톡을 강제로 매각하는 길을 열어주었다
On 23 April, the legislation passed the Senate, and will now be sent to Mr Biden to be signed into law.
This is not the first time American authorities have struck out at TikTok.
Former US President Donald Trump tried to ban the app when he was in the White House in 2020.
But Mr Trump - now confirmed as the Republican candidate for the 2024 presidential election - has criticised the new legislation, arguing that limiting TikTok would unfairly benefit Facebook.
When could a TikTok ban happen?
Even after Mr Biden signs the bill, the ban won't take effect immediately.
In fact, it would likely take several years before Americans are unable to access the app, as ByteDance sues - likely all the way to the Supreme Court - to block the forced sale.
Also, the legislation gives ByteDance nine months to sell TikTok to an American buyer, with an additional three-month grace period, before any ban would take effect.
That means that the sale deadline would most likely come some time in 2025, after the winner of the 2024 presidential election takes office. If Mr Trump wins, he may seek to block the ban from being implemented.
How would a TikTok ban work?
The most straightforward way for the US to ban TikTok would be to remove it from app stores, such as those operated by Apple and Google for iOS and Android devices.
App stores are how most people download apps on to their smartphones and tablets, so the ban would stop new users from getting TikTok.
앱스토어는 대부분의 사람들이 그들이 이용하는 스마트폰과 타블렛에 앱을 다운로드하는 수단이므로 앱을 금지하는것은 새로운 사용자들이 틱톡을 다운로드 하지 못하게 되는것이다
That means people who already had the app would no longer be able to get future updates designed to improve security or fix bugs.
The US bill forbids applications controlled by US adversary countries from being updated and maintained in the US.
It gives broad powers to the president to limit apps with ties to Russia, China, Iran and North Korea.
What has TikTok said it will do about the legislation?
TikTok has been highly critical of the legislation, calling it an affront to the US right to free speech.
Chief executive Shou Zi Chew warned the bill would give "more power to a handful of other social media companies", and put thousands of American jobs at risk.
ByteDance would have to seek approval from Chinese officials to sell TikTok, but Beijing has vowed to oppose such a move.
How have TikTok users in the US responded?
Some US creators and users have also criticised the proposed ban.
Tiffany Yu, a young disability advocate from Los Angeles, told the BBC at a protest outside the White House the platform was vital to her work.
TikTok asked its 170 million US users to contact their political representatives and ask them not to support the bill.
But the deluge of "confused" calls from TikTok users to congressmen and senators may have backfired.
Several politicians say the campaign has worsened the concerns they have about the app, and strengthened their resolve to pass the legislation.
Is TikTok banned in other countries?
If the bill becomes US law, it could inspire similar moves elsewhere.
TikTok is already banned in India, which was one of the app's largest markets before it was outlawed in June 2020.
It is also blocked in Iran, Nepal, Afghanistan and Somalia.
The UK government and Parliament banned TikTok from staff work devices in 2023, as has the European Commission.
The BBC also advised staff to delete TikTok from corporate phones because of security fears.
How does TikTok work and how much user data does it collect?
At the heart of TikTok is its algorithm.
This is a set of instructions within the app which determines which content is presented to users, based on data about how they engaged with previous material.
Users are offered three main feeds on their app - Following, Friends and For You.
The Following and Friends feeds present users with content from people they have chosen to follow and who follow them back, but the For You feed is automatically generated by the app.
This curated feed has become the main destination for users looking for new content, and creators hungry for the millions of views TikTok videos can clock up if they go viral.
Critics say the app collects more data than other social media platforms in order to power its highly personalised system.
This can include information about users' location, device, the content they engage with and keystroke rhythms they exhibit while typing.
But popular social media apps such as Facebook and Instagram collect similar data from users.
Joke-What's Got You Down Pal?
There’s a guy sitting at a bar, just looking at his drink. He stays like that for half an hour.
Soon, a big trouble-making truck driver steps next to him takes the drink from the guy and just drinks it all down.
The poor man starts crying.
The truck driver says, “Come on man, I was just joking. Here, I’ll buy you another drink. I just can’t stand seeing a man crying.”
“No, it’s not that. This day is the worst of my life.
First, I fall asleep, and I’m late to the office. My boss, in an outrage, fires me.
When I leave the building to my car, I found out it was stolen.”
“The police say they can do nothing.
I get a cab to return home and when I leave it, I remember I left my wallet and credit cards there. The cab driver just drives away.
I go home and when I get there, I find my wife in bed with the gardener.
I leave home and come to this bar.”
“And just when I was thinking about putting an end to my life, you show up and drank my poison.”
