Volume 2 is proof Muller was hunting for a pony he could ride, and not investigating.
Making it easy for an “investigator” who has clearly already made his mind up ... is just stupid. Especially after the hounding of Hatfill in the anthrax case. It’s not obstruction to demand the investigators play by the rules.
The real obstruction of justice was in diverting DOJ resources and personnel from their duties to instead serve the political agenda of the Democratic Party.
