Oh boy, the reaction to this must've been something

to see; fly on the wall, etc. All bolds mine:
Dear Attorney General Holder:

As our investigation in Operation Fast and Furious has progressed, we have learned that senior officials at the Department of Justice (DOJ), including Senate-confirmed political appointees, were unquestionably aware of the implementation of this reckless program. Therefore it is necessary to review communications between and among these senior officials. As such, please provide all records relating to communications between and among the following individuals regarding Operation Fast and Furious:

1. David Ogden, Former Deputy Attorney General;

2. Gary Grindler, Officer of the Attorney General and former Acting Deputy Attorney General;

3. James Cole, Deputy Attorney General;

4. Lanny Breuer, Assistant Attorney General;

5. Kenneth Blanco, Deputy Assistant Attorney General;

6. Jason Weinstein, Deputy Assistant Attorney General;

7. John Keeney, Deputy Assistant Attorney General;

8. Matt Axelrod, Associate Deputy Attorney General;

9. Ed Siskel, Former Associate Deputy Attorney General;

10. Brad Smith, Office of the Deputy Attorney General;

11. Kevin Carwhile, Section Chief, Capitol Case Unit; and

12. Joseph Cooley, Criminal Fraud Section.

These records should include e-mails, memoranda, briefing papers, and handwritten notes. Additionally, any records related to communications referring to a large firearms trafficking case within the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) or in Phoenix should be included in any production.
Full letter at Sipsey, or at Codrea's link.

This has to have some people saying bad words and reviewing their(they hope) legal cover; this covering 'a large trafficking case and/or in Phoenix' covers Houston and Tampa and anywhere else they may have been running such an operation. Which brings up another "If you lie to us, when we catch it, we won't be happy" moment for these people.
