US energy giant Chevron on Tuesday asked its employees around the world to remove WeChat from their work phones, making it one of the first US companies to respond to Trump's executive ban.
In an email to employees, Chevron listed WeChat as a "non-compliant application" and asked those who had the app installed on their work phones to remove it within a few days or be disconnected from the company's network.
"Due to a recent Executive Order banning the use of WeChat, Chevron is requiring that you remove the application from your mobile device," the email reads. "If no action is taken, prior to September 27, 2020, your access to the Chevron system will be removed."
Chevron also confirmed the operating system and model number of each employee's phone.
WeChat was one of the targets of the Trump administration's restrictions ahead of the US elections in November.
According to Trump's executive order, WeChat was supposed to disappear from US app stores on Sept. 20.
But a judge in San Francisco issued a preliminary injunction over the weekend, calling Trump's order a violation of free speech rights.
WeChat has 19 million regular users in the US and more than 1 billion worldwide.
The app encompasses many features, including games and digital payments, and is a marketing and communication tool often used by US companies to reach their Chinese counterparts or consumer audiences.
