Congress only has jurisdiction over the CIA. As the intel community has made perfectly clear over the past year of denying and slow-walking documents. Justice falls under Administration - an equal part of government to Congress, and subject to the direct orders not of Congress, but of the President.
Pelosi/Schumer/Schiff/Warner could be looked at as unindicted co-conspirators if they are attempting to interfere with Administration jurisdiction. (tongue in cheek on that last bit)
We have control of the congress HOWEVER with LYIN RYAN at the helm lord only knows what he will do to stop Intelligence agency from releasing docs!!!! This NEEDS to drop before the midterms!!!!
