The Supreme Court on Monday said it would not review the conviction of former Illinois governor Rod Blagojevich on corruption charges.

The justices without comment let stand an appeals court ruling that said Blagojevich (D) illegally sought money in exchange for filling the Senate seat left vacant when President Obama was elected.

Blagojevich is serving a 14-year sentence for that and other actions he took as governor. An appeals court threw out five of his 18 convictions, and the former governor wanted the justices to find that the others did not cross the line from political favors to criminal conduct.

The court next month will hear an appeal from former Virginia governor Robert McDonnell (R), who was convicted of corruption for his efforts on behalf of a businessman who bestowed money and gifts on the governor and his family.

The court on April 27 will hear oral arguments in the long-running saga of McDonnell, who was convicted along with his wife, Maureen.
