The federal government’s star witness — former ComEd executive Fidel Marquez — took the stand in the ComEd bribery trial Monday, as prosecutors plan to use secretly recorded FBI conversations to spotlight a key contract used to pay associates of former House Speaker Mike Madigan.
Marquez, who is expected to remain on the stand for several days, agreed to cooperate with investigators in 2019 and secretly recorded his colleagues who are now on trial: former ComEd CEO Anne Pramaggiore, ex-ComEd lobbyist John Hooker, former ComEd lobbyist Michael McClain and onetime City Club President Jay Doherty.
