I do believe you may have hit on something. It begs the next question who has done him in?
I surmise the chef shared some drug with one or both of the girls—who understandably might be a bit rebellious after years in the WH with those two.
Those two, however, were well acquainted with drugs, which gave the green light to the kids to do what dad did. Chef may have scored the drug, but apparently couldn’t handle it.
I can’t imagine Obamas having the guy offed intentionally...even if he intended to expose all their dirty underwear. Very unbecoming of an X-Prez.
