Washington: Twitter has used a new policy to identify misleading content for the first time on a post retweeted by US President Donald Trump that appeared to show Democratic Party rival Joe Biden endorsing his re-election.
The social media platform has struggled with removing deceptive and abusive content in the past, but has also faced accusations its curbs have suppressed some political views.

A clip posted by White House social media director Dan Scavino appeared to show Biden telling a crowd: "We can only re-elect Donald Trump." The footage was later retweeted by Trump and had been viewed nearly six million times by Monday.
But the video cropped the end of Biden's sentence -- made during a recent campaign speech Missouri state -- where he was discussing the need for party unity in the wake of a bruising primary contest.
"We can only re-elect Donald Trump if in fact we get engaged in this circular firing squad here," Biden had said.
Twitter appended a label to the video describing it as "manipulated media," prompting a denial from Scavino in a later tweet on Monday.
The platform last month suspended dozens of accounts for spam-like posts supporting former Democratic presidential hopeful Michael Bloomberg, whose campaign hired hundreds of people to promote him on social media.
