WASHINGTON — President Trump has once again mocked Gov. Gavin Newsom’s dyslexia as “disqualifying” for leadership, marking at least the fourth time in a week that the president has targeted the California Democrat for being open about his diagnosis.

In remarks Monday in the Oval Office, Trump said Newsom was “dumb” and should never be allowed to be president because he has “admitted that he has learning disabilities, dyslexia.”

“That’s how crazy it’s gotten with a low-IQ person,” Trump said. “Honestly, I’m all for people with learning disabilities but not for my president. ... And I know it’s highly controversial to say such a horrible thing.”

But in the course of his needling, Trump mistakenly elevated his political rival to the rank of commander in chief — repeatedly referring to Newsom as “the president of the United States.” Newsom took the opportunity to turn the tables on the president.

“I, GAVIN C. NEWSOM, AM OFFICIALLY PRESIDENT OF THE UNITED STATES (THANK YOU DONALD!)” he wrote on X Monday.

The clash is the latest in a storied contest of chest-beating between Trump and Newsom, who have made sport of bad-mouthing one another across campaign rallies, interviews and social media.

The president has frequently cast Newsom as a symbol of the liberal governance he opposes, while the governor has leaned into the confrontations, often using them to elevate his national profile and position himself as a leading Democratic counterweight. His sparring with the president appears to be part of an aggressive strategy to amplify his own messaging as he weighs a potential run for president in 2028. This time, Newsom used the spotlight to support young people with dyslexia.

“To every kid with a learning disability: don’t let anyone — not even the President of the United States — bully you,” Newsom wrote on X. “Dyslexia isn’t a weakness. It’s your strength.”

The insults first materialized when a video went viral of Newsom speaking at a book tour appearance with Atlanta Mayor Andre Dickens during which he discussed his lifelong struggle with the learning disability. Since then, the president has repeatedly poked at the vulnerability.

Trump has brought up the governor’s dyslexia at least four times in the last week. He mentioned it at a political rally in Kentucky last week, where he equated dyslexia with a “mental lack of ability,” and again during a Fox News Radio interview on Friday, in which he reiterated that “presidents can’t have a learning disability.” In a post on Truth Social, Trump labeled Newsom’s admission a “politically suicidal act,” calling him “dumb” and “A Cognitive Mess!”

After the Kentucky rally, Newsom responded to Trump.

“I spoke about my dyslexia, I know that’s hard for a brain-dead moron who bombs children and protects pedophiles to understand,” he said.

Dyslexia affects as much as 20% of the population, according to the Yale Center for Dyslexia and Creativity. Despite affecting a such a wide portion of the population, the condition is widely misunderstood, according to dyslexia researcher Dr. Helen Taylor of the University of Cambridge.

“In some ways, Trump’s awful comments are just a cruder version of assumptions that already run through our culture,” she said. “If anything, (it’s) the opposite. There is evidence of an overrepresentation of people with dyslexia in business leadership roles.”

According to Taylor, there is a link between dyslexia and “enhanced abilities” in areas such as discovery, invention and creativity.

“The same cognitive trade-offs that can make routine tasks like reading more difficult support strengths in navigating complexity and guiding groups toward better future outcomes,” she said.

Newsom often describes his early experiences with dyslexia as a source of insecurity when he was growing up. In his memoir, the governor writes about his mother, Tessa Newsom, attempting to help him with homework. The lessons ended with him “running out of the room screaming that I didn’t know what was wrong with my brain.”

Back when Newsom was a boy in the 1970s, dyslexia was recognized but still not fully understood. He recalls a day when his mother grew so concerned that she took a deep breath and told him, “It’s OK to be average, Gavin.”

“I understood even back then that this, too, came from her deep reservoir of love for me,” Newsom writes in his book “Young Man in a Hurry.” “But I don’t recall crueler words ever said about me.”

The challenges from his learning disorder persist in his work at the state Capitol. Newsom finds reading off a teleprompter challenging. His aides describe days of painstaking preparation before major addresses to live audiences. Late edits to a speech, and the resulting changes to the words on the screen, threaten to throw off his delivery.

All memos in the governor’s office are written in 12-point Century Gothic font with specific spacing between lines, formatting that his aides say helps him with his disability.

The governor reads his daily briefings a few times in the morning, underlines sentences and writes down notes to retain the information on yellow cards he keeps in his suit pockets.

The ritual, he has said, helps him compensate for his dyslexia and feel confident communicating. But it also adds to the public perception of Newsom as a smooth-talking, and at times rehearsed, politician. His excessive preparation has become a trait he considers a “super power.”

His effort to thoroughly absorb reading material and desire to understand issues before he speaks about them means he’s often well-prepared. In his perception, the learning disorder has brought out his grit and resilience, and helped him hone other skills, such as quickly reading a crowd.

It has also sharpened his memory.

At a news conference revealing his budget proposal in 2020, a reporter asked the governor what he would do to address 500,000 housing units that had been approved by developers in California, but hadn’t been constructed.

Without missing a beat, Newsom directed the journalist to the exact page in his 246-page budget that touched on the issue.

“While people with dyslexia are slow readers, they often, paradoxically, are very fast and creative thinkers with strong reasoning abilities,” according to the Yale Center for Dyslexia and Creativity.

The governor’s wife, Jennifer Siebel Newsom, discussed the president’s attacks Tuesday in a video on X in which she emphasized that “learning differences do not determine someone’s potential.” She listed a number of qualities she considered disqualifying for the presidency, including being a convicted felon, bankrupting businesses, having numerous associations with convicted sex offender Jeffrey Epstein, and sending “masked extremists to terrorize Black and brown communities and rip kids away from their families.”

“Everything that Donald Trump represents is frankly beyond disqualifying,” she said. “Day in and day out, Trump says things that make him unfit for office. He degrades our vulnerable communities, our institutions, even the Constitution itself.”

Two of the Newsoms’ four children have also been diagnosed with dyslexia.
