The battle over TikTok heads to court

Driving the news:

• TikTok confirmed Saturday that it plans to sue directly over the impending ban.
• TikTok’s suit is expected to come later Monday, sources told Axios.
• TikTok has said there was no due process in Trump's abrupt move to ban the app.

Between the lines: The Wall Street Journal reported Sunday that the government action against TikTok was preceded by an aggressive behind-the-scenes lobbying push by Facebook and its CEO, Mark Zuckerberg.

Meanwhile: A group representing WeChat users, per the Wall Street Journal, has sued over Trump's planned ban of the messaging platform, also used for a raft of other functions by people in China and those who do business in the country.

• The Trump administration is privately telling U.S. companies they can keep doing business with WeChat in China even if it's banned in the U.S., Bloomberg reported Friday.

• Without that allowance, products like Apple's iPhone could become far less appealing in China, where WeChat is central to most people's digital lives. It could even dent sales outside of China considering all the people who rely on WeChat to communicate with loved ones in China or to do business there.
