President Donald Trump's late-night Truth Social posting sprees reveal a pattern that mental health professionals might say warrants serious concern, according to one of the president's biographers. Journalist Michael Wolff, who has written four books about Trump, discussed Trump's social media habits on a new episode of "Inside Trump's Head," a podcast he co-hosted with Hugh Dougherty, the Daily Beast's executive editor, on Thursday. A recent review of Trump's posts by The Daily Beast found that the president has made more than 8,000 posts since returning to office in January. The review found that the president did not post on just five or six nights in April, and he was repeatedly posting during hours when most adults are asleep. Trump's posts have also contained some concerning content. For instance, he's claimed that former President Barack Obama is guilty of treason and should be imprisoned. He's also posted several times alleging that the 2020 general election was stolen from him, even though his lawyers have failed to prove that point in more than 60 court cases since he lost the election. "You can look this up and find the President of the United States regularly saying things that are out of control, bizarre, unhinged, irrational — that have in every possible way departed reality," Wolff said. "If this were a family member of literally anybody who stayed up all night and posted sometimes 100 posts of this kind of wingnut stuff, that would be a mental health crisis."Wolff, who has covered Trump for more than a decade, also said it is concerning how little attention Trump's late-night posting sprees have gotten in the media. "There are no headlines in the New York Times that say the president of the United States has flipped his lid," he said, "which in any reasonable, fair-minded reading of what he posts on social media, that's the conclusion you would come to."
