Mr Gianforte, a Republican, told lawmakers that a wider ban would further "our shared priority to protect Montanans from Chinese Communist Party surveillance."

The video-sharing app, owned by Chinese company ByteDance, is accused of posing a national security risk through data gathered from millions of users.

Over the coming weeks TikTok said it would publish educational content and host briefings with influencers and advertising agencies "so the rules of the road are abundantly clear when it comes to paid content around elections".

Cloudfare said it tracks data using its tool Cloudflare Radar, which monitors web traffic.
