There was NO EXECUTIVE PRIVILEGE ASSERTED WHATSOEVER when McGahn testified to Mueller. Why does the sb prez think he can assert it NOW?

Is the sb prez REALLY that ignorant? Still? Why didn't he assert it to begin with? That would have prevented the turmoil that occurred subsequently. But NO. So now when the sb prez sees what a colossal enormous hugely  bigly gargantuan SCREWUP it was he wants to take it back. Too late. Sheesh. Dumb does not come any dumber than him AND HIS ATTORNEYS WHO OKAYED IT! As I said. The detritus. The dregs. The dumbest of the dumb. Only they would work for the sb prez. .
