DOJ is going to hold ATF at arm's length while holding their collective noses, claiming that it was "within ATF" and DOJ wasn't in on the details.
(Well, except for U.S. Attorneys Lanny Breuer, Burke, and Hurley)
US Attorneys making US foreign policy with Mexico? Without consulting their superiors?
Either a DOJ run wild, with no respect for the chain of command at all, or a lie. I'm going to guess lie.
