The on-going investigation into Bridgegate isn’t going to stop anytime soon. The legislative committee looking into the incident has filed four more subpoenas in the matter. Among those who have been told to cooperate are Michael Drewniak, the spokesman for the governor. The committee is investigating if the story presented by the governor’s office is plausible or whether additional abuse of power took place. Gov. Chris Christie claims he had no prior knowledge to the incident before it took place.
