Niki Haley is in a tizzy because Trump has not put heavier sanctions on Russia. I think Trump wants to calm down Russia; not cause further antagonism. Niki wants to push things to end up in a war with Russia, in my opinion. That or she’s stupid.
Niki also announced Trump will keep troops in Syria to continue fight against Isis. Trump was planning to pull them out of Syria.
I have little doubt that if Nikki Haley gets too far off the reservation Trump will have a little talk with her.
PS - should have added - unless this is a ploy to keep adversaries and others in the dark about what POTUS will actually do or is doing, which is also a distinct possibility.
