TRENTON -- Citing newly released polls, Assemblyman John Wisniewski (D-Middlesex) renewed his call Tuesday evening for Gov. Chris Christie to answer questions from lawmakers under oath.

Wisniewski, a 2017 candidate for governor, cited an FDU PublicMind poll released Tuesday that found 71 percent of voters thought the governor should have been a defendant in the federal Bridgegate trial.

Christie has maintained he knew nothing about the lane closures before or during the four-day traffic jam, which resulted in the conviction of two top allies and a guilty plea of a third.

"We didn't need a poll to tell us what we already know," said Wisniewski in an email sent to media.

"The people of New Jersey are smart and they aren't buying Governor Christie's claims of ignorance. We need to finish this investigation with Governor Christie under oath...When you compare testimony given to the legislature to that given in federal court, someone is lying."

A Quinnipiac University poll released on Tuesday also showed a majority of New Jersey voters believe the governor's involvement in the George Washington Bridge scandal "should be investigated further" by a margin of 56 percent to 41 percent.

However, Wisniewski lacks the support of top Democratic leaders needed to haul the governor in front of lawmakers.

Last month, while Senate Majority Leader Loretta Weinberg (D-Bergen) called for the start of impeachment hearings against the governor, Senate President Steve Sweeney (D-Gloucester) argued that there were more pressing issues, and that "we need to move forward in the state."

Assembly Speaker Vincent Prieto (D-Hudson), has also taken a dim view of Wisniewski's call to reignite the Joint Select Committee on Investigation.

A spokesman for the governor did not immediately return a request for comment.
