Twitter has expanded its policies on election related misinformation, by either adding fact-checking labels or hiding tweets that have 'false or misleading information that causes confusion' about elections; ' officials and institutions executing' elections; tweets with unverified information about 'election rigging, ballot tampering, vote tallying, or certification of election results'; and 'misleading claims about the results' of elections which 'calls for or could lead to interference with the implementation of the results of the process', including 'claiming victory before election results have been certified, inciting unlawful conduct to prevent a peaceful transfer of power or orderly succession'. The platform says it will label or remove posts that break the rules, but it did not provide details of which processes will be used to determine whether a tweet shall be removed or just labeled. In the past, Twitter hid US President Donald Trump's tweet that encouraged supporters to vote twice, which is illegal under US law.
