Attorney General Eric Holder has already turned over 7600 documents and testified nine times before congress. The ATF agent in charge and AG Mike Mukasey, who started the program under George W Bush when it was called operation "Wide Receiver", have never been called to testify. If congress really wants to get to the bottom of this, why hasn't everyone involved been called?
If the House of Representatives vote next week to sanction Holder, from what I understand, they could have him handcuffed and taken right to the jail in the capital. I can't think of a better photo-op to energize the progressive base.
