Paul notes below that Harriet Miers' apparently discussed firing Debra Yang, the US Attorney from Los Angeles who was investigating then-House Appropriations Chair Jerry Lewis (R-CA) as part of the expanded Cunningham investigation. Let's not forget though. Yang did leave. Yang stepped down on January 1st 2007, though she has said she was not forced out.

Whatever the story with Yang, we are looking at a series of US Attorney resignations that we'll call 'resignations of concern', departures where the departing USA has either refused to comment on why they left or denied being pushed but in rather unconvincing ways. Minnesota and Western District of Missouri are two other cases we're looking at very closely, among others.
