A special Illinois House committee is going to investigate the conduct of Speaker of the House Mike Madigan. It could finish in discipline for Madigan and in the most extreme case wind up with him being expelled from the House Chambers.

The move comes at the request of some House Republicans. Madigan hasn’t been indicted in connection with a federal bribery case surrounding ComEd. The utility admitted in a deferred prosecution agreement this summer that they bribed Madigan associates to gain his support for laws that paved the way for ComEd to raise electric rates.

Democrat Governor JB Pritzker says he wants all the answers surrounding ComEd and hopes this isn’t a political move ahead of the November elections.

The speaker says in a statement that he “never made a legislative decision with improper motives”. The committee was formed with three democrats and three republicans.
