(CNN) - U.S. Attorney Patrick Fitzgerald is seeking court approval to provide Illinois lawmakers with partial tapes of four of Gov. Rod Blagojevich's wiretapped phone conversations.
Fitzgerald's decision follows a request from the Illinois House of Representatives' Special Investigative Committee, which is considering impeachment charges against the Illinois governor.
In a motion filed Monday, Fitzgerald wrote, "Although many relevant communications were intercepted, the government believes that, on balance, it is appropriate to seek the disclosure of four intercepted calls, in redacted form, to the Committee, and that disclosure of the calls by themselves would not interfere with the ongoing criminal investigation."
The motion emphasizes prosecutors do not take a position on whether Blagojevich should be impeached.
The motion also says that while U.S. law "does not necessarily require the government to obtain judicial authorization before disclosing intercepted communications to other law enforcement or investigative officers, the government does so here out of an abundance of caution and in order to afford
the interceptees in the recorded calls an opportunity to be heard and to object, if they so choose."
Blagojevich's attorney Ed Genson was testifying Monday before the Illinois House panel and could not be reached for comment on Fitzgerald's court motion.
As part of his testimony, Genson made a more general comment about the wiretapped conversations.
"The fact is, nothing happened," he said. "There is nothing in that tape or affidavit saying that anybody was propositioned, acknowledging that they were talked to. There is nothing in that tape that shows that people were asked to give money or campaign contributions or anything. It's just talk. That's what it is, unfortunate talk, talk that shouldn't have been made, perhaps, but not actions."
FBI agents arrested Blagojevich on December 9 after federal prosecutors alleged, among other things, that he had tried to "sell" Obama's former Senate seat. Blagojevich denies any wrongdoing.
