Trump says he is open to Musk buying TikTok

U.S. President Donald Trump said on Tuesday he was open to billionaire Elon Musk buying social media app TikTok if the Tesla CEO wanted to do so.

The short video app used by 170 million Americans was taken offline temporarily for users shortly before a law that said it must be sold by its Chinese owner ByteDance on national security grounds, or be banned, took effect on Sunday.
