President Donald Trump’s decision to issue an executive order Monday delaying enforcement of the federal ban on TikTok has deepened a murky legal landscape in the US for the popular social media app and its technology partners.

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.

Shortly after taking office Monday, the president issued the order to delay the app’s ban for 75 days. The law went into effect on Sunday.
