  Twitter experienced considerable growth during the COVID-19 pandemic in 2020. The platform also was increasingly used for misinformation related to the pandemic. Twitter started marking tweets which contained misleading information, and adding links to fact-checks. In May 2020, Twitter moderators marked two tweets from U.S. President Donald Trump as "potentially misleading" and linked to a fact-check. Trump responded by signing an executive order to weaken Section 230 of the Communications Decency Act, which limits social media sites' liability for content moderation decisions. Twitter later banned Trump, claiming that he violated "the glorification of violence policy". The ban drew criticism from conservatives and European leaders, who saw it as an interference on freedom of speech.
