Only two options regarding AG Barr - there is a plan or there is not.
1) if there is a plan, POTUS and team know exactly what they have in Barr. This is not something you leave to chance when you are reshaping the western world.
2) there is no plan and then it doesn’t matter if Barr is DS or not. We are in for a shitstorm at some point.
Comes down to what you believe.
