The clip Trump promoted suggested that CNN would have spun the viral video to make it appear negative. The latest tweet, posted a few hours ago, shows what is an altered version of a popular video that went viral on social media previous year, which shows a black toddler and a white toddler hugging.
The video Trump shared begins with footage of the boys running set to ominous music, with a fake misspelled CNN caption reading, "Terrified todler runs from racist baby".
After Trump tweeted the video it quickly went viral, racking up millions of views in less than two hours.
Twitter describes the designation as applying to tweets that "deceptively promote synthetic or manipulated media that are likely to cause harm".
Our thought bubble, via Axios' Kyle Daly: Twitter seems to be growing more comfortable with checking Trump after years of being criticized for holding him to different standards than other users. We'll continue working with facts and invite you to do the same, rather than tweeting fake videos that exploit innocent children.
The video closes by claiming that "America is not the problem".
It's probably fair to say Donald Trump has a love-hate relationship with Twitter.
It was widely reported on, including by CNN, which ran the video under the headline: "These two toddlers are showing us what real-life besties look like".
