Mr. President, one of the first things you'll get upon your swearing in is a stack of resignation letters from all the U.S. Attorneys, standard procedure when changing Administrations. The very first one you should act on is that of Patrick Fitzgerald, U.S. Attorney for the Northern District of Illinois.
I know you want to be all bi-partisan like you said during the campaign, and keeping campaign promises is certainly laudable. I think you are wrong that stuff like having Rick Warren give the invocation at your Inauguration will foster a spirit of bipartisanship, because I don't think this crop of Republicans have it in them, but you've certainly earned the right to find that out in your own way.
There is, however, something more important than campaign promises, more important even than your aspirations to "set a new tone" in Washington. That, Mr. President, is your Duty as laid out in the Constitution.
