OK, just for the record, I think this is the final answer on this question of an 18-day gap in the Justice Department emails.
The gap supposedly occurred between November 15, 2006 when the Justice Department asked for White House approval for the purge plan, and December 4, when the White House gave the green light. DOJ spokesman Brian Roehrkasse has responded that it's less a gap than a "lull."
In any case, here are all the emails that readers have found in the interim:
Yesterday, we turned up a November 29th email concerning a DoJ evaluation of U.S. Attorney for San Francisco Kevin "Company Man" Ryan.
Thinkprogress turned up an email chain between DoJ officials regarding obscenity prosecutions between November 20th and the 22nd.
Here's another email from December 1 with an exchange between a DoJ official and former Karl Rove aide Tim Griffin, about when Griffin would start work as the U.S. Attorney for Little Rock. We've also found a similar email between the same two on November 16th.
So that's that. Four email exchanges over the 18 day period.
Now, of course, the really interesting email traffic in this period would have been within the White House. But the administration is determined not to turn that over.
