Microsoft says it is still discussing a potential purchase of TikTok, days after President Donald Trump said he would ban the popular short-form video app from operating in the United States.

In a blog post Sunday (local time), Microsoft said its CEO Satya Nadella has talked with Trump about buying the app, which is owned by Chinese start-up ByteDance.

US policymakers have for weeks expressed concerns about the app as tensions between the United States and China escalate, with many asserting that it could pose a national security risk.
