Donald Trump rallied a crowd of young supporters with a colorful airing of grievances Saturday night, just days after becoming the third president in American history to be impeached.

“Crazy Nancy, she’s crazy,” the president said of House Speaker Nancy Pelosi.

“So now she says she has no case, so let’s not submit it. That’s good right? But you know what, so unfair. She has no case,” Trump said, lingering on Pelosi’s decision to, at least temporarily, withhold the articles of impeachment in a bid to force Senate Republicans to hold a fair trial.

Trump’s remarks came as he kicked off his two-week winter getaway with the keynote address to Turning Point USA’s annual student action summit here, not far from his Mar-a-Lago resort. It was a chance to bask in the love of some of his fiercest supporters, with scores of 20-somethings donning “Make America Great Again” hats and rhinestone “TRUMP” hair clips.

But people on Twitter pointed something out…Trump didn’t look good, and at one point, his body actually spasmed.

Trump neurologically malfunctions w/ a full spasm. Note his shoulders involuntarily jerk as he slurs. Thx @karenamyatt & @ChuckWa74233336 for the heads up. Trump desperately needs a neurological eval at a quality facility like the Mayo Clinic. Not Walter Reed which reports to WH pic.twitter.com/ct6S5Pln2d

Twitter had some thoughts:

It's absolutely astounding a sitting president can hide serious physical and mental health issues. He can go completely mad and they won't do anything.

Holy crap! Tom, is this real? That is probably one of the more dramatic instances I’ve seen of him with the spasm and the momentary inability to correctly Pronounce a word… he definitely seems aware because he always trys to transition to another word or phrase.

Wow, this is by far the worst we have seen him. We’ve seen him stumble on his words but his body movement is extremely alarming. What I just can’t understand why his handlers continue to ignore this and not seek treatment for him immediately that he may be having a stoke.

I honestly don't think I've seen anything as bad as this yet. He jerks, loses what he's talking about, and tries to recover by switching to something else immediately. This is sad.

Wow. That spasm is remarkable + alarming. How long will Trump's handlers keep pushing him onto stage? He tries to cover for his medical events by using the verbal em dash as he snaps himself out of his spasm — "Look, you remember this …?" These events seem to happen daily now.

What in hell was that? There is something very wrong with his neurological function. NO ONE CARES ENOUGH TO GET HIM HELP.
