I can't begin to understand why Holder would write a response to Congress making denials before he had even seen the subpoena. Surely he of all people understands the value of not making statements you don't have to make. Interesting to see how that plays out for him.
And that attack on Issa, & Congress, will include something to the effect of, "if we had proper gun control, the ATF wouldn't have had to do this."
"If there were more laws prohibiting the sale of guns to prohibited persons, ATF would not have had to circumvent numerous laws prohibiting the sale of guns in order to arm Mexican cartels!"
Its a succinct PR statement; but I don't know that it is a good one for DOJ. I feel comfortable I can offer a reasonable alternative to that argument
