(If this has been diaried before, please show me where and I'll take down.)
Somehow, Paul Kiel at TPM Muckraker has gotten hold of an email exchange between Abu Gonzo Chief of Staff, Kyle Sampson, and then W.H. Counsel, Harriet Miers, which describes a list of "USAs to be pushed out."
This would seem to refute Gonzo's assertion to Congress that he:
"...would never, ever make a change in a United States attorney for political reasons or if it would in any way jeopardize an ongoing serious investigation. I just would not do it." link
In the email, a jpeg of which is available HERE, Sampson writes to Miers:
"I am only in favor of executing on a plan to push some USAs out if we really are ready and willing to put in the time necessary to select candidates and get them appointed -- It will be counterproductive to DOJ operations if we push USAs out and then don't have replacements ready to roll immediately. In addition, I strongly recommend that as a matter of administration, we utilize the new statutory provisions that authorize the AG to make USA appointments.... we can give far less deference to home state senators and thereby get 1.) our preferred person appointed and 2.) do it far faster and more efficiently at less political costs to the White House."
For my money, all that is left is for some enterprising Kossack to prove how this email is not, in itself, an impeachable offense, at least as far as Gonzales is concerned.
