Trump doesn’t fold. He repositions.
This is the nugget in Mitch’s statement, “Further, negotiations on DHS will be prioritized over consideration of any other funding bills.”
I hope that this is the position that Mitch takes during negotiations. “No, we will not discuss DOJ. EPA etc. until we have an agreement on DHS and border wall funding. Period. DHS must be voted on by the house and signed by the President before we deal with the other agencies.”
