As he walked toward the presidential aircraft, Trump repeatedly moved one hand toward his leg, a gesture that quickly became the focus of social-media commentary. There is no medical evidence presented with the video establishing that Trump's leg-tapping is connected to dementia or any other neurological condition. The repeated motion could represent anything from a habitual gesture to a self-soothing movement, but no public medical assessment has established why Trump was tapping his leg. One widely circulated post claimed Trump's hands appeared to be "rotting," while another user compared his fingers to "stuffed sausages." The latest Air Force One footage therefore offers considerably less certainty than the online reaction surrounding it suggests.
