Twitter adds fact-check warnings to Trump tweets

For the first time, Twitter has flagged some of 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.

Until now, the president has simply blown past Twitter’s half-hearted attempts to enforce rules intended to promote civility and “healthy” conversation on its most prominent user. Trump frequently amplifies misinformation, spreads abuse and uses his pulpit to personally attack private citizens and public figures alike — all forbidden under Twitter’s official rules.
