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.

President Donald Trump has directed his Justice Department to pause enforcement of the TikTok ban until early April, but a host of questions remain - including whether Trump has the authority to issue such an order and if TikTok’s China-based parent would be amenable to selling the popular social media platform.
