United States lawmakers are concerned TikTok users' data is being accessed by China.  

The House of Representatives has passed a bill that would ban the social media platform if Chinese tech giant Byte Dance doesn't sell its stake within six months.  

It will now go to a vote in Senate. 

US correspondent Mitch McCann told Mike Hosking that there's a lobbying campaign by TikTok underway.   

He says they've hired influencers to talk about the success they've had with TikTok and the impact on small business in America.
