(AP) -- CHICAGO - Ousted Gov. Rod Blagojevich's most recent chief of staff, former chief fund-raiser and another Illinois political insider all pleaded not guilty today.
They're facing charges that accuse them of taking part in what prosecutors allege was widespread state government corruption.
Blagojevich pleaded not guilty two days earlier to plotting to sell or trade President Barack Obama's vacant U.S. Senate seat and a tangled web of other corruption.
Former chief of staff John Harris, former fund-raising chairman Christopher Kelly and Springfield power broker William Cellini appeared before U.S. District Judge James Zagel to enter not guilty pleas.
Harris is cooperating with prosecutors, and his attorney told Zagel they hope to have an agreement on a change of plea before the end of May.
