The US House of Representatives overwhelmingly approved a bill on Wednesday that would force TikTok to divest from its Chinese owner or get banned from the United States.
The lawmakers voted 352 in favour of the proposed law and 65 against, in a rare moment of bipartisan unity in politically divided Washington.
The legislation threatens to be a major setback for the video-sharing app, which has surged in popularity across the world while causing nervousness about its Chinese ownership and its potential subservience to the Communist Party in Beijing.
The fate of the bill is uncertain in the Senate, where some key figures are apprehensive of making such a drastic move against an 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.
