Via the Washington Post, Twitter labeled a Trump video as "manipulated media" last night:

Twitter on Thursday evening took the rare step of appending a warning label to one of President Trump’s tweets after the company determined it violated its policies on manipulated media.

The president tweeted a doctored version of a popular video that went viral in 2019, which showed two toddlers, one black and one white, hugging. In the version Trump shared, the video has been edited with ominous music and a fake CNN headline that says, “Terrified toddler runs from racist baby.”

“Racist baby probably a Trump voter,” the headline then says in a subsequent screen.

The video then cuts to the original clip of the children hugging, and then cuts to the message “America is not the problem. Fake news is.”

"The president of the United States was censured by Twitter for posting a video of a racist baby" is another of those headlines that would have been totally baffling five years ago and now doesn't even make you blink https://t.co/tPHej2l32j
