TikTok, the video sharing platform, potentially faces being banned in the US following legislation brought forward by senator Marco Rubio.
Introducing the act to the Senate on Tuesday, Rubio wants transactions from social media companies under the influence of China and Russia banned.
Legislation was also put to the House of Representatives.
“TikTok is digital fentanyl that’s addicting Americans, collecting troves of their data, and censoring their news,” said representative Mike Gallagher in a press release.
Rubio added: “This isn’t about creative videos — this is about an app that is collecting data on tens of millions of American children and adults every day.”
He also accused Beijing-based TikTok owner ByteDance of “reporting to the Chinese Communist Party,” although the tech firm has previously denied the allegations.
TikTok suggested the legislation represented “a politically-motivated ban that will do nothing to advance […] national security”.
It had previously issued a statement on 8 December about how it was “bolstering compliance and security” in America,
Several US states have already banned TikTok from being used on government devices and networks due to fears about how data is collected and used by ByteDance.
Members of the US Federal Communications Commission and former president Donald Trump have also called for Tik Tok to be outlawed.
In August, a UK Parliamentary TikTok account was closed over similar fears, with TikTok subsequently confirming in November that some China-based workers could access European data.
