The chairman of a New Jersey legislative panel investigating the George Washington Bridge lane closures said Gov. Chris Christie's top aides had engaged in a "cover-up" and the governor could be impeached if it is determined he was aware of efforts to use the bridge for political purposes.
"Using the George Washington Bridge, a public resource, to exact a political vendetta, is a crime," New Jersey Assemblyman John Wisniewski, who is spearheading the bridge probe, told NBC News on Saturday. "Having people use their official position to have a political game is a crime. So if those tie back to the governor in any way, it clearly becomes an impeachable offense."
In a news conference on Thursday, Christie denied any prior knowledge of plans to use lane closures on the bridge as political payback against the Mayor of Fort Lee for refusing to endorse his re-election. He said he was "stunned by the abject stupidity that was shown here."
