The head of the ATF has met with the Committee on Oversight and Reform with just his personal attorney. He went outside the DOJ for this meeting. Rep. Issa and Sen. Grassley sent a scathing letter to Eric Holder.
What emerges is that the DOJ attempted to control the investigation by limiting the access by Congress to those with direct knowledge of the matter, and more importantly the role that DOJ and executive officials played in the Fast and Furious operation.
This is really fascinating, aside from the emerging scandal, but also in light of Obama's instructions for ICE to not prosecute certain kinds of illegal immigrants, many of which hail from Mexico.
