You are constantly in spin mode for the Orange Fat Ass, eh?
Unlike you, I abhor being a hyperpartisanm mindless parrot. The first think to come to your mind: "how do I defend, my hero, Trump?". My mind is free thinking and operates independently. So with that said, I actually think you have a valid point. Adult men are not always obligated to dignify false accusations by tendering a response. Some of us lefties have been on message boards long enough to understand your point: it is often not worth dignifying the false accusations of socially inept, resentful losers with a response. I get it.
Jarod had a point though. Tillerson evidently went out of his way to deny a lot of things. But when presented with an opportunity to deny the moron claim, he demurred.
