U.S. Attorney Patrick Fitzgerald wants lawmakers to hear what Gov. Rod Blagojevich says on wiretapped phone calls.
Fitzgerald filed paperwork Monday to release conversations caught on wiretaps to the Illinois House committee moving ahead to impeach Blagojevich.
Federal prosecutors have asked a judge for permission to disclose a limited number of the intercepted conversations in a redacted form.
Fitzgerald says disclosing four calls wouldn't interfere with the ongoing criminal investigation.
Blagojevich was arrested Dec. 9 on federal corruption charges.
The governor is accused of trying to sell President-elect Barack Obama's vacant U.S. Senate seat to the highest bidder, but he's denied any wrongdoing.
