Donald Trump set off a wave of irony on Thursday when he declared during a Cabinet meeting: “I don’t want a stupid person being president.”

The remark came amid a lengthy attack on Democrats, whom he branded “a party of insanity” that “will destroy our country.”

Trump singled out California Gov. Gavin Newsom, a potential 2028 Democratic presidential candidate who has spoken publicly about his dyslexia, a brain-based learning difference that affects reading and language processing.

“I believe he took himself out of the running when he says he suffers from mental disability,” Trump said, referring to Newsom by his derogatory nickname “Newscum.”

“A reporter said it was terrible that I talked that way about somebody with mental disability,” he added, before calling Newsom “actually a very stupid person.”

“I don’t want a stupid person being president,” Trump continued, later boasting about acing multiple cognitive tests — which he claimed proves he is smart, even though such tests are designed to detect cognitive decline, not measure intelligence.

Newsom’s press team fired back: “Wow. Trump is going to resign?”
