Valerie Jarrett? Really?

No, I'm not surprised either.
Practically lost in the 1,000-plus pages of records is an index that shows Jarrett was brought in to manage the fact that Holder lied to Congress after the story about the disastrous gun-running operation broke in the media. 
...
The files received by JW include three electronic mails between Holder and Jarrett and one from former U.S. Attorney Dennis Burke to Jarrett. The e-mails with Holder are all from October 4, 2011, a significant date because, on the evening of October 3rd, Sheryl Attkisson (then at CBS news) released documents showing that Holder had been sent a briefing paper on Operation Fast and Furious on June 5, 2010. The paper was from the director of the National Drug Intelligence Center, Michael Walther.

This directly contradicted Holder’s May 3, 2011 testimony to the House Oversight and Government Reform Committee, during which he stated that he, “probably heard about Fast and Furious for the first time over the last few weeks.” The October 4, 2011 date may also be significant because it came shortly after the August 30, 2011 resignation of U.S. Attorney for Arizona Dennis Burke and reassignment of acting ATF director Kenneth Melson to the position of “senior forensics advisor” at DOJ.
Remember, in non-legal speak 'directly contradicted' means 'proves he lied his ass off'.
