USDA Under Secretary for Farm and Foreign Agricultural Service Jim Miller has resigned from the USDA. This might sound like boring or routine news but I think it is actually significant. Miller was a favorite of Sen. Kent Conrad (D-ND), who he worked for on the Senate Ag Committee before moving over to the USDA. From the rumors I heard, Miller's role within the USDA was to keep Kathleen Merrigan from doing anything too "organic-y" (if you know what I mean).
At this point, there's no word on why he resigned, but it's fairly normal to have turnover in high level government positions like this. I wouldn't be too surprised if Miller left because he was offered a high paid lobbying position for Big Ag... or if he left for another reason but gets a lobbying job all the same. I also wonder how this will change things around the USDA, and who will be chosen to replace Miller for the remainder of Obama's term.
