The U.S. Commerce Department prohibitions on the Chinese messaging app WeChat, scheduled to kick in on Sunday, will be suspended after a judge signs a renewed motion for a preliminary injunction against Trump's ban on WeChat, Cao Ying, one of the founders of U.S. WeChat Users Alliance (USWUA) said on Saturday.

After the Commerce Department issued a prohibition on transactions relating to WeChat on Friday, the USWUA, a New Jersey-based nonprofit organization created by a group of lawyers, filed a renewed motion for a preliminary injunction in court on Saturday. 

The USWUA claimed that the decision from the Commerce Department to ban the use of WeChat across the country contradicts to what the U.S. Department of Justice promised on Wednesday in court, which is that if U.S.-based users download and use WeChat for personal or business purposes, they would not be regarded as breaking the president's executive orders and be exempt from "criminal or civil liability," Ying Cao Law LLC said in a WeChat post on Saturday. 

After an emergency hearing on Saturday afternoon, the judge ruled that the plaintiff, USWUA, draft a preliminary injunction, Cao said in the post. She said the judge would then sign the injunction to suspend the prohibition but did not reveal when the judge will sign it. 

The Commerce Department's decision issued on Friday was in response to President Donald Trump's two executive orders signed in August, banning U.S. transactions with WeChat, a messaging app owned by Tencent, and TikTok, a video-sharing app owned by ByteDance. 

The two executive orders were scheduled to go into effect on Sunday, but the ban on TikTok has been postponed while the company makes a proposed deal with Oracle and Walmart. 

After the executive orders were issued, the USWUA filed a lawsuit to have the ban overturned, seeking to prevent them from prohibiting WeChat use in the U.S. by individual users, businesses and groups, as for the app is the primary way many U.S. users communicate with their family members and run businesses in Chinese communities. 

"We understand that WeChat is an app with its problems and issues. However, it should be our own choice to decide whether to use it or not. Mr. President has no right to make such a choice for us," the alliance said in an open letter published on August 8.
