Joint Program Steering Group (JPSG)
I believe that the DoJ and the DoD have been working together for some time now. It only makes sense because of the mix of foreign and domestic threats.
There's the little agreement called the Joint Program Steering Group (JPSG) that represents both departments is staffed with members from several agencies.
I'm still doing more digging on this stuff…
