Trump’s shaky performance during his commencement address at West Point, where he apparently had trouble negotiating a ramp and handling a water bottle, had folks openly wondering about his physical health. Naturally, Trump took to Twitter to defend himself, claiming the “very long & steep” ramp (it wasn’t) was “very slippery” and had “no handrail.” He went on to claim he ran the last ten feet (debatable) due to “Momentum!”
