President Trump and Collusion: (If he has a normal version of multiple personality) Which of his personalities know, and when did they know it?

In occasional past posts, I have speculated that President Trump has a normal version of multiple personality (normal to the extent that it does not cause him distress or dysfunction).

These speculations were prompted by his past use pseudonyms (the names of alternate personalities?), various public personas (various personalities incognito?), childlike behavior (child-aged alternate personalities?), a peculiar pattern of lying, and third-person self-reference. Most of these behaviors have been repeatedly discussed by New York Times columnists, but without reference to multiple personality, per se.

The title of this post is a play on the famous Watergate question, “What did he know, and when did he know it?” For a person with multiple personality, the question might be: “Which personalities knew, and when did they know it?” or, more concisely, “Who knew?”
