Demanding excellence from a contractor that takes on work in a 5 Star Hotel is NOT bullying, no more than if you had contracted for new counter tops in your home and a contractor did awful work, as happened to me. I took him to court and in the end I had to pay another company a lot more to redo the mess the first contractor did.
As far as your "playing with the big boys now and they will cut him off at the knees" it sounds like an act of bullying itself.  It is Congresses job to make legislation, it is the President that approves through veto power or not what they generate.  That is NOT bullying, that's called "separation of powers".
