Twitter flags Trump's tweets with fact-checking warnings

For the first time, Twitter has flagged some of US President Donald Trump’s tweets with a fact-check warning.

On Tuesday, Twitter added a warning phrase to two Trump tweets that called mail-in ballots “fraudulent” and predicted that “mail boxes will be robbed,” among other things. Under the tweets, there is now a link reading “Get the facts about mail-in ballots” that guides users to a Twitter “moments” page with fact checks and news stories about Trump’s unsubstantiated claims.
