in addition to the normal fear a derp like Linda would have of the generals, add in the fact that Linda is a military officer, I think Army. He was a JAG off, of course, but it’s still military. He’s not being watched by Trump’s advisors, he’s being watched by his commanding officers. His look is that of a recruit in his skivvies getting chewed out by his Drill Sergeant for having pissed in his bunk.
I think Gen. Kelly looks like a very nice man. I suspect Gen. Mattis is wickedly funny, hell I KNOW he is from the things that have been made public. “I heard you were the devil incarnate and I wanted to meet you.”
