At least from the governor's perspective, the Bridgegate scandal is behind him. But who is going to pick up the tab for the investigation?

Governor Chris Christie at South River Town Hall (Governor's Office/Tim Larsen)

Was Chris Christie doing his due diligence to protect the office of the governor and the state? Or was the governor's hiring of a law firm to conduct an investigation a total self-serving measure?

According to reports, the investigation's cost was 1 million in legal fees. But the question is, who should pick up the bill? Should the state and NJ's residents foot the bill or should the governor pay for it himself out of his own pocket?
