Notes on the New Random: Head Gear

What with Trump embracing Netanyahu, I noticed an odd fact about Rex Tillerson, Trump’s choice as the new Secretary of State. Tillerson has quite gray hair, but the graying has not been uniform. The back of his head, when seen in profile, indicates black hair. And at certain times and from certain angles, he seems to be wearing a yarmulke. Was that fact one, or perhaps even the most important, reason for his choice as Secretary? To be pleasing to Israel? Or was it Mr. Tillerson’s friendship for a man who rarely wears a hat at all?
Concerning headgear, I have not been privileged to read the classified portions of the Intelligence Establishment’s report on alleged Russian hacking of the U.S. election process. Therefore I cannot confirm a rumor that is said to be “in the air” (or is that just “fake news”?)—namely that the color of Mr. Trump’s favorite electioneering baseball cap was chosen by Mr. Putin, the color red being, as it were in Mr. Putin’s background.
