US WeChat users sue President Donald Trump over order banning messaging app

Some US-based users of WeChat are suing President Donald Trump in a bid to block an executive order that they say would effectively bar access in the U.S. to the hugely popular Chinese messaging app.

The complaint, filed Friday in San Francisco, is being brought by the nonprofit U.S. WeChat Users Alliance and several people who say they rely on the app for work, worship and staying in touch with relatives in China.

The plaintiffs said they are not affiliated with WeChat, nor its parent company, Tencent Holdings.

In the lawsuit, they asked a federal court judge to stop Trump’s executive order from being enforced, claiming it would violate its U.S. users’ freedom of speech, free exercise of religion and other constitutional rights.
