US President Donald Trump has granted TikTok a 75-day extension to comply with a law that requires the hugely popular video app to either sell its US assets or face a ban in the country. "We do not want TikTok to 'go dark'. We look forward to working with TikTok and China to close the Deal," Trump wrote on Truth Social on Friday. The platform is currently owned by Chinese company ByteDance. Trump's first extension took effect in January and was set to expire on Saturday.
