The written transcript of this 60 Minutes show from last night can be read here. From the transcript:
As correspondent Scott Pelley reports, 52 former state attorneys-general have asked Congress to investigate whether the prosecution of Siegelman was pursued not because of a crime but because of politics.
Those AG's are from both sides of the aisle. The real story is that Karl Rove was involved in the plan to sink Siegelman..which of course makes this whole case suspect as hell and politically motivated.
