Ousted Illinois Gov. Rod Blagojevich pleaded not guilty Wednesday to revised federal corruption charges and challenged prosecutors to allow jurors to hear all of the FBI’s recordings of his telephone conversations.

Sounding unusually combative after the brief hearing, Blagojevich told reporters he would not ask Judge James B. Zagel to prevent jurors from hearing FBI wiretaps in which prosecutors say he schemed to sell or trade President Obama’s former Senate seat.
