President Donald Trump has signed an executive order Monday to keep TikTok operating for 75 days, a relief to the social media platform’s users even as national security questions persist.

An executive order is an instruction from the president which has the weight of the law behind it. But Trump's order does not overturn the ban. Instead it tells the US attorney general not to enforce the law for now - something experts had expected would be his first move.

Trump said the government should be a half owner of TikTok's U.S. business in return for keeping the app alive, and threatened China with tariffs if it failed to approve a deal.
