CHICAGO — Two months ahead of trial, federal prosecutors late Tuesday revealed new details of wiretapped conversations and other evidence they intend to use against four people accused in an alleged bribery scheme between Commonwealth Edison and then-House Speaker Michael Madigan.
Among the new revelations:
— A ComEd lawyer is expected to testify that the man accused of orchestrating the scheme, ex-lobbyist Michael McClain, had such a longstanding and close relationship with Madigan that he was sometimes referred to within ComEd as a “double agent.”
