Secret robot legs or maybe frontotemporal dementia...

In the clip, Trump is seen standing on stage, though rather than standing straight, he appears to be leaning forward. David drew comparisons between the stance and Michael Jackson's iconic lean from the Smooth Criminal video.

He also raised the possibility that it could be connected to a specific health condition: "Now, this alone doesn't tell us anything definitive about Trump, but there is a position that is common to people suffering with frontotemporal dementia in which they sort of lean forward exactly the way Trump is doing right now.

"Now, it is not the gravity-defying lean of Michael Jackson's Smooth Criminal, but it's sort of going in that direction, and it's very weird. And Trump's upper body is forward. His legs seem to somehow be behind him."
