Theory: AG Barr is fully briefed on the intel aspects of this operation, which demonstrate exactly what went on and who was involved in both planning and execution. This intel cannot be publicly exposed because there are operations in progress and because of the usual sources and methods issues (likely FISAs obtained on foreign operatives inside and outside the US). The intel does, however, point directly to the areas requiring investigation and that is the essence of the prosecutorial mandate to the US Attorneys around the country.
Something is definitely happening. Let’s see whether the US Attorneys move as quickly as the exigent circumstances require.
