Fred Kaplan wonders in Slate. After some informative context setting, Kaplan cuts to the chase:

“And so we are left to ponder the final, most puzzling question: Why did Trump hang on to these documents? What could he gain from doing so? Some on Twitter speculate that he might want to sell the documents to foreign governments. I wouldn’t put much past Trump, but even I consider this theory extremely unlikely. (That said, storing these materials at a public place like Mar-a-Lago is stunningly irresponsible. It is proper that the FBI also sought surveillance video showing who was wandering into the storage area.)

My guess about Trump’s motives (and, at this point, it can only be a guess): pure, testosterone-driven ego.

The Washington Post reported back in February, when the National Archives retrieved 15 boxes of materials from Mar-a-Lago, that Trump retained much of his correspondence, including the ‘love letters’—as he once described them—with North Korean dictator Kim Jong-un. The Post attributed this information to ‘two people familiar with the’ documents. This suggests that Trump showed the letters to people. Who were these people? We don’t know. Was he showing the letters in order to show off? It seems likely.”

Put me firmly in the “might want to sell the documents to foreign governments” camp. That’s what I concluded when the story started to take shape. There’s a lot I don’t understand about The Former Guy, but there is one thing I believe to be irrefutable. Having more money has always been his primary motivation. Follow the obsessive drive for more money.

And if your righty friends try to ruin your weekend with talk of Hillary’s emails, lay this little bit of Kaplan on ’em:

“While we’re on the subject, what about Hillary’s email? Of the 30,000 emails that the FBI examined, eight were found to contain Top Secret information. Seven of them were about CIA drone strikes, which had been reported in the newspapers (but were still technically classified). The other one was an account of a telephone conversation with the president of Malawi. (All conversations with foreign leaders are, by definition, Top Secret.) In other words, she revealed nothing remotely about nuclear weapons, signals intelligence, or anything that might have enlightened a foreign spy.”

When it comes to cattle futures, Vince Foster, and Benghazi, you’re on your own.
