Twitter is alive with tweets about Trump’s health, pointing to a video showing him walking very slowly and unsteadily down a ramp after he addressed graduates at West Point, accompanied by an officer. Another clip from his speech showed him taking a drink of water during his speech and using both hands to steady his grip. These clips produced the hashtag #TrumpIsNotWell, and many clips of Obama bounding up and down steps, even one of Obama drinking water from a glass with one hand.

Trump responded with a defensive tweet that brought additional attention to the mishaps.

The Washington Post reported:

BRIDGEWATER, N.J. — President Trump late Saturday tried to explain his slow and unsteady walk down a ramp at the U.S. Military Academy at West Point, which had generated concern and mockery on social media, by claiming the walkway was “very slippery” and that he was worried about falling.

The walk in question came at the conclusion of Saturday’s commencement exercises at West Point, where Trump was the guest speaker. As he exited the raised platform by descending a ramp alongside Lt. Gen. Darryl A. Williams, the academy’s superintendent, Trump was visibly tentative and took short, careful steps.

Video of the moment was widely shared on social media, with critics of the president — including Republican operatives working on the Lincoln Project, an anti-Trump group whose ads have provoked the president’s ire — using the hashtag #TrumpIsNotWell in their tweets.

The chatter seemed to get the attention of Trump, who is spending the weekend at his golf club in Bedminster, N.J. At 10:57 p.m. Saturday, the president wrote on Twitter: “The ramp that I descended after my West Point Commencement speech was very long & steep, had no handrail and, most importantly, was very slippery. The last thing I was going to do is ‘fall’ for the Fake News to have fun with. Final ten feet I ran down to level ground. Momentum!”

Elements of Trump’s explanation strained credulity. Trump’s claim that the ramp had been “very slippery” was inconsistent with the weather, which on Saturday in West Point, N.Y., was sunny and clear-skied. The grass plain on which the commencement took place was dry.

In addition, Trump wrote that he “ran down” the final stretch of the ramp. Video footage of the episode shows the president picking up his pace slightly for the final two steps, but that would hardly be considered a run or a jog by any standard definition.

Once on flat ground, Trump appeared to walk normally as he surveyed the field and mingled with officers on his walk to board Marine One, which was parked roughly 100 yards or so from the platform stage.

The ramp video was not the only clip from Trump’s speech to generate considerable attention on social media. Another was when he briefly took a sip of water while standing behind the presidential lectern. As Trump raised a small glass of water toward his mouth with his right hand, he used his left hand to steady the bottom of the glass so he could take a sip.

Some defenders of Trump say that its unfair to criticize Trump for any physical disability, but bear in mind that this is a man who ridiculed a reporter with disabilities, raided questions about Hillary Clinton’s fitness, raises questions about Biden’s health, and never acknowledges any infirmity. It matters very much to the public to know whether the president’s physical and mental health is diminished.
