On 11 October 2016, a video purportedly showing a 1969 campaign spot called "Dope Man" promoting Fred Trump, father of President Donald Trump, for election as mayor of New York City was posted to the "Historical Paroxysm" channel on YouTube, described as "A test ad for Fred Trump's aborted mayoral campaign against John Lindsay."
Athough Historical Paroxysm has since deleted their video, another version was uploaded to YouTube:
The primary clue that this video is fabricated comes from its source, the "Historical Paroxysm" YouTube channel, which states in its about section that the video shares "found footage from alternate realities."

The ad gained greater prominence when it was referenced in an essay by Sidney Blumenthal published by the London Review of Books. The section mentioning the ad was eventually removed, and a disclaimer addressing it was added at the bottom of the article:
A paragraph referring to Fred Trump’s campaign for mayor of New York, although it accurately reflected Trump’s racial attitudes and his hostility towards Mayor John Lindsay, has been removed because the campaign ads referred to appear to be clever fakes.
