One of Donald Trump’s first acts as president will be to rescue TikTok, one of America’s favorite social media obsessions, his allies tell The Washington Post.

Social media platform TikTok is hurtling toward a U.S. ban that could upend its business and frustrate more than 150 million American users -- unless President-elect Donald Trump finds a way to reverse the policy.

TikTok's Chinese parent, ByteDance, is locked in a legal battle that could see it banned in the U.S. over national security concerns, but the new president could affect that outcome.
