It’s the first time the social network has enforced a new policy to fight doctored videos and photos

In this case, the altered video of Biden — who has surged to the front of the Democratic race to oust Trump in November — is based on a speech he gave in Kansas City, Mo., on Saturday. It was then shared on Twitter by Scavino, only edited to make it appear as if Biden inadvertently endorsed Trump for reelection.
The version of the video shared by Scavino showed Biden stumbling on a line during a speech, then saying, Excuse me. We can only re-elect Donald Trump.

But the edited video deleted the second part of the former vice presidents sentence. The whole thing said: Excuse me. We can only reelect Donald Trump if in fact we get engaged in this circular firing squad here. Its gotta be a positive campaign.
Twitter applied the label to Scavinos tweet at about 5 p.m. on Sunday evening, about 18 hours after Scavino first shared the video. The video had at least 5 million views and more than 21,000 retweets as of Sunday evening.
Twitters roll out of the new label was not without technical glitches, however. The label was not showing up when people searched for Scavinos tweet, though Twitter spokeswoman Katie Rosborough said it was appearing in individuals timelines. She added the company is working on a fix.
The misleading label is one way social media companies are trying to crack down on false and misleading information in 2020, following a 2016 election in which they were widely blamed for allowing incorrect information to widely circulate on their platforms, influencing the election and providing Russian trolls and bots with entry into the American political system.
But the companies are not acting in tandem and their policies are inconsistent. Facebook, too, has a policy for manipulated video, and says it will remove deepfake videos that meet certain criteria. It also has partnerships with third-party fact checkers, and applies labels to videos those organizations determine are false.
Twitters new policy prohibits sharing synthetic or manipulated media that could cause harm. But like in this instance, the company may apply labels to tweets to help people understand their authenticity or to provide additional context.
Its rare for Twitter to take action against tweets shared by Trump, even though there have previously been complaints that the presidents tweets violate the companys policy. Twitter has previously taken action against the presidents tweets for copyright violations.
The White House and the Biden campaign did not immediately respond to requests for comment.
