US President Donald Trump signed an executive order that seeks to limit liability protections social-media companies enjoy after Twitter Inc. began selective fact checks of his posts on the platform.

Under current law, companies like Twitter and Facebook Inc. are protected for users’ posts. Trump told reporters that his order “calls for new regulations under section 230 of the Communications Decency Act to make it that social media companies that engage in censoring or any political conduct will not be able to keep their liability shield.”

Trump’s move comes after Twitter earlier this week labeled two of his posts about mail-in voting “potentially misleading” and provided links to news coverage of his comments. The president responded with outrage, accusing the social media company of censorship and election interference and threatening to possibly shut down the service.
