I think most people by now understand that Trump is not the easiest guy to work for and like most of the rest of DC is probably not a completely moral person either. But the way the left jumps on and reports every little criticism like this is I think having the opposite effect to what they intend. The "boy who cried wolf" effect is just so strong right now that even legit criticisms are starting to get ignored, even by people like me who don't much care for Trump. The over the top way the left and their media have treated this president would be a good thing IF, and only IF, they would treat all other politicians the same way......they don't and they won't.
I'm sure there have been dicks in the white house before, I'm sure there have been corrupt people in the white house before, I'm sure other presidents haven't kept up on briefings before (this was a big criticism of Obama too BTW). And I'm sure all or some of these same traits will appear in future presidents. Again IF we the people would hold all of them to the same standard instead of letting the letter by their name decide who we criticize and who we don't, then maybe we could find presidents who aren't extremely flawed....but we don't and we won't.
And even if what Tillerson say here is 100% true, guess what, I still prefer Trump over Hillary because of SCOTUS, taxes and regulations....those three things are worth a lot of crap from the person in the white house.
