FORT LEE — The Democratic lawmaker investigating September's controversial lane closures at the George Washington Bridge has subpoenaed any correspondence on the matter between Gov. Chris Christie and Port Authority officials.

State Assemblyman John Wisnieswki (D-Middlesex) wants to know what the governor knew about the closures and when he knew it.

The subpoenas, issued to key officials of the bistate agency, demanded "all documents and correspondence, produced between Aug. 1, 2013 and the present date between Governor Chris Christie or any member of his administration and/or any employee, officer, or executive of the Port Authority." The subpoenas give the officials until Thursday to respond.

Abruptly and without warning, the agency closed two of three local access lanes Sept. 9 to 13, turning Fort Lee streets into a parking lot for five days and angering commuters and local officials accustomed to advance notice.

Christie has denied any involvement in the closures, which have attracted national attention due to the Republican governor’s widely anticipated run for president in 2016. The Democratic National Committee and a group with ties to Hillary Clinton, a potential Democratic candidate for the White House, have pounced on the scandal.

Apart from Wisniewski’s investigation, state Sen. Loretta Weinberg (D-Bergen) said today she would introduce a resolution Thursday asking New Jersey’s congressional delegation to review the Port Authority’s original charter, granted by an act of Congress in 1921. Weinberg said she was concerned that agency’s bistate nature leads to internal conflicts that generate rogue decision-making of the kind involved in the lane closures.

Wisniewski shared her concern, wondering whether an "iron curtain" divided New Jersey officials from New Yorkers.

Subpoenas demanding gubernatorial correspondence were issued to Port Authority Executive Director Patrick Foye, and to the two Christie-backed officials who have resigned from the agency amid the scandal, Deputy Executive Director Bill Baroni and his subordinate, Director of Interstate Capital Projects David Wildstein.

Baroni testified last month that he knew of the closures in advance, though he said Wildstein ordered them.

This is Wisnewski’s second round of subpoenas; the first summoned Port Authority officials to a Dec. 9 hearing before the Assembly Transportation, Public Works and Independent Authorities Committee, which Wisniewski chairs. Foye’s testimony seemed at odds with Baroni’s earlier explanation that the closures were related to a traffic-safety study. Foye, an appointee of Democratic Gov. Andrew Cuomo of New York, told the committee he was never told of any such study and remained unaware of one.

To Wisniewski and other Democrats, Foye’s testimony supported their suspicions that the real motivation for the closures was retaliation against Fort Lee’s mayor after he refused to join other urban Democrats who crossed party lines to endorse Christie’s re-election.

The governor’s office declined to comment on the subpoenas. Instead, his spokesman referred to a news conference Friday, when Christie announced Baroni’s resignation from the agency, acknowledging that mistakes had been made in how the closures were implemented while reiterating that he was not involved.

The Port Authority and the three agency officials issued subpoenas did not respond to requests for comment.
