I'm pretty sure they admitted responsibility for guns from AZ just to the US Attorney, one guy whose last name was Burke who resigned, and the ATF in AZ. They didn't accept responsibility for guns walked from Texas or Florida, the latter being called Operation Castaway.
Realizing that this is election eve, there are many reasons to rid ourselves of this regime, but this one and Benghazi in which so many people were murdered in cold blood by our own government should be on top of the pile. Unfortunately, very few people even know about either one. G-d help us defeat these bloody monsters.
