Why was Tik Tok expelled from the United States?

Wen | Xie Jiu finally kills Tik Tok.
First, the US government required that ByteDance must sell Tik Tok's US business.
Later, US President Trump considered comprehensively banning Tik Tok in the US by executive order.
On July 31, Trump said, "We will prohibit them from operating in the United States.
Of course, I have the right to do so.
I can prohibit them by issuing administrative orders." On August 1, Tik Tok's parent company, ByteDance, agreed to spin off its US business and began to negotiate with Microsoft about the sale.
After once opposing Microsoft's acquisition, Trump's attitude has changed.
According to Trump's latest statement on August 3, he does not oppose Microsoft or other American companies to acquire TikTok.
If TikTok cannot be sold before September 15, it will be banned in the United States.
Trump also said that if TikTok was successfully sold, the US government should also receive a part of the remuneration, "because we make this transaction possible".
In recent years, Tik Tok came out, becoming the most famous application in the international market in China.
In particular, after the outbreak of the epidemic this year, the global blockade has led to billions of people staying at home, which has stimulated young people's demand for short videos.
In the first half of this year, TikTok has been downloaded more than 600 million times, ranking first in the world.
The most popular old brand social software in the United States is out of reach.
However, Tik Tok's success overseas is also full of controversy.
The biggest controversy is suspected of collecting user data.
In 2019, TikTok was fined $5.7 million for violating the United States Children's Privacy Act.
The US politicians are more worried that the Tik Tok data may endanger the US national security, especially considering the Chinese background of Tik Tok, which makes the problem easier to be magnified.
In November last year, an American think tank said that Tik Tok would collect user data.
If the information collected was sent back to China, it might pose a security threat to the United States and other Western countries.
In particular, many young people in the U.S.
military also like to play Tik Tok, and their short videos may expose some confidential information.
Some U.S.
senators also said last year that TikTok has been downloaded more than 110 million times in the United States, bringing national security risks to the United States, and requested the U.S.
intelligence department to conduct a national security risk assessment and report it to Congress in a timely manner.
As a result, Tik Tok's data security issues began to come to the table.
In response to the concerns of the United States, Tik Tok said that all of Tik Tok's US user data was stored in the United States, and there was a backup server in Singapore.
However, the United States initiated a security investigation.
Last November, the Committee on Foreign Investment in the United States began to intervene to investigate national security threats.
This time, Tik Tok was forced to sell its US business, which was also dominated by the agency.
