The US House of Representatives will vote Wednesday on a bill that would force TikTok to cut ties with its Chinese owner or get banned in the United States.

The legislation is the biggest threat yet to the video-sharing app, which has surged to huge popularity across the world all while causing intense nervousness amongst governments and security officials about its Chinese ownership and its potential subservience to the Communist Party in Beijing.

The vote is likely to occur at 10:00 am (1400 GMT) and is expected to pass overwhelmingly in a rare moment of bipartisan entente in a politically divided Washington.

The fate of the bill is uncertain in the Senate, where key figures are against making such a drastic move against an intensely popular app that has 170 million US users.

President Joe Biden will sign the bill, known officially as the “Protecting Americans from Foreign Adversary Controlled Applications Act,” into law if it came to his desk, the White House has said.

The measure, which passed unanimously through committee last week, would require TikTok’s parent company ByteDance to sell the app within 180 days or see it barred from the Apple and Google app stores in the United States.

It would also give the president power to designate other applications to be a national security threat if under the control of a country considered adversarial to the US.
