Why does Issa want Pickering and Mullen to talk behind closed doors
so the public can't see? Because Pickering for one is not going to be bullied. He already told Issa what he said is "not true." Referring to Issa's claim Pickering wouldn't attend the first hearings. Pickering isn't taking their garbage. Issa lied sitting right next to the man he was lying about. Why are people like Issa, Paul, Graham, Bachmann, etc, not discharged from Congress due to malfeasance?
Wow, Pickering said it 'was not true', so I guess that makes it the gospel of the political Gods. Surely no one would suggest that someone in Washington was not telling the truth? Don't look know but there are tons of unanswered questions about this fiasco and Pickering knows the answers to more than a few of them.
Congressman Issa is probably a good attorney, and as such he probably has a pretty good idea as to what the answers to most of the questions that he will ask of any witness, and as in any deposition the answers to some questions may lead to further insights into this affair (i.e., the Benghazi cover up) and unanticipated further questions, and lastly the answers provided may prove embarrassing to either man if given in public.
Bottom line: a private deposition should provide an environment for candor that might not be available in a public hearing.
