“It was Willie Brown,” Mr. Trump, who spent much of the last year hoping to make gains with Black voters, posted. “But now Willie doesn’t remember?”

Mr. Brown, 90, who was mayor of San Francisco and speaker of the California Assembly, gave several interviews on Thursday and Friday saying such a trip never occurred.

Turns out, however, that there was a Black politician from California who once made an emergency landing in a helicopter with Mr. Trump. It just wasn’t Mr. Brown.

Mr. Holden said that he called Mr. Brown to compare notes. Mr. Brown told him he had never been in a helicopter crash with Mr. Trump.

“I said, ‘Willie, you know what? That’s me!’” Mr. Holden said. “And I told him, “You’re a short Black guy and I’m a tall Black guy — but we all look alike, right?”

Mr. Holden gave his own height as 6-foot-1. “Willie has to be about 5-foot-6. Maybe 5-foot-5. He comes up to about my shoulders. And he’s bald. And I’m not bald.”

Mr. Brown, he said, “just laughed and laughed.”

Mr. Holden, summing up his assessment of Mr. Trump’s recollection, said: “I just think he makes things up. That’s what I think. He never thought anybody’s going to check.”
