Twitter tags Trump tweet with fact-checking warning
presidential election in the US
A post by US President Donald Trump has been given a fact-check label by Twitter for the first time.
Mr Trump tweeted, without providing evidence: "There is NO WAY (ZERO!) that Mail-In Ballots will be anything less than substantially fraudulent."
Twitter put a warning label in the post and linked to a page that described the claims as "unsubstantiated".
Mr Trump on Wednesday threatened to "strongly regulate" or even "close down" social media platforms.
