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.

Within hours of his inauguration, President Donald Trump issued an executive order suspending the enforcement of a TikTok ban that had taken effect the previous day. The move tossed a lifeline to TikTok -- and its 170 million users in the United States.
