Asked to recall his graduation from the University of Pennsylvania, Donald Trump obliged with so few details he might have been reading from a children’s book.

“The weather was beautiful,” he once told the Boston Globe. “My parents were there, and it was a nice day.”

We can fill in a few more details from the historical records of that ceremony — exactly 50 years ago, May 20, 1968, the same year that 16,899 U.S. soldiers died at the peak of the Vietnam War.

Trump posed for a photo that day with his beaming father, whose real estate fortune he was destined to inherit. Not yet 22, he half-smiled, and his arms hung limply from the cuffs of his robe.
