Wikipedia often reflects what the last editors got into it just before you looked, but here's what they have today:
In June 2007 a Republican lawyer signed a sworn statement that she had heard five years ago that Karl Rove was preparing to politically neutralize Siegelman with an investigation headed by the U.S. Department of Justice.<7> Siegelman defenders point out that over 100 charges were thrown out by three different judges, and the investigating U.S. Attorney was the wife of his political opponent's campaign manager.<7> The Republican activist, lawyer Dana Jill Simpson of Rainsville, Alabama, filed a sworn statement saying that she was on a Republican campaign conference call in 2002 when she heard Bill Canary tell other campaign workers not to worry about Siegelman because Canary's "girls" and "Karl" would make sure the Justice Department pursued the Democrat so he was not a political threat in the future.<7> "Canary's girls" included his wife, Leura Canary, who is United States Attorney for United States District Court for the Middle District of Alabama.<7> Leura Canary only submitted recusal paperwork after Siegelman Attorney David Cromwell Johnson's press conference in March of 2002. Then two months after the press conference she "voluntarily recused herself."
Jill Simpson later stated that she did not infer that Karl rove was involved in a plot: 'Jill Simpson, the Republican Rainsville lawyer who wrote the affidavit, said in an interview that she is not responsible for how others interpret her sworn statement. She said she tried to accurately represent a conference call she heard in which Rove's name came up, and she said no one definitively said in that call that Rove arranged for Siegelman's investigation. It's not clear if Rove was being identified in the call as the person behind the investigation or as someone who heard Siegelman already was under investigation.'.<8>"Affidavit about Siegelman case open to debate", The Birmingham News, July 8, 2007. Retrieved on 2007-07-08. </ref>
Siegelman defenders noted the sentence and fine are unusual because, for example, former Alabama Governor Guy Hunt, a Republican, was found guilty in state court of personally pocketing $200,000, and state prosecutors sought probation, not jail time, in the Hunt case.<7>
The New York Times noted, "The United States attorneys scandal has made clear that partisan politics is a driving force in the Bush Justice Department," and "There is reason to believe prosecution may have been a political hit, intended to take out the state’s most prominent Democrat, a serious charge that has not been adequately investigated."<9> Further, "We hope that the appeals court that hears Mr. Siegelman’s case will give it the same hard look that another appeals court recently gave the case of Georgia Thompson. Ms. Thompson, a low-level employee in a Democratic administration in Wisconsin, was found to have been wrongly convicted of corruption by another United States attorney."<9>

Looking forward to more real information.
