Gov. Chris Christie's 2013 re-election campaign has been issued a subpoena for documents relating to meetings that were allegedly canceled with Jersey City Mayor Steven Fulop, who declined to endorse the governor during the last election, The Wall Street Journal reported Wednesday.

The subpoenas were issued by U.S. Attorney Paul Fishman just over a month after an interim report probing the 2013 lane closures at the George Washington Bridge was released, stating that there is no conclusive evidence showing Christie played a role in the scheme to close lanes or knew about it as it happened. The Wall Street Journal reported that the subpoenas "are another sign that the yearlong probe into former allies of Mr. Christie has broadened beyond matters directly related to the George Washington Bridge lane closures."

No one from the Christie Administration would comment on the subpoenas, The Wall Street Journal reported.

The accusations regarding the canceled meetings came last January. Fulop, a Democrat, alleged that meetings proposed by the Christie administration in 2013 were called off after he refused to support the governor in his bid for re-election.

"The Christie administration accused Mr. Fulop at the time of being partisan and prioritizing his own political agenda. Mr. Fulop is said to be eyeing a run for governor in 2017," according to The Wall Street Journal article.

In September, access lanes to the George Washington Bridge in Fort Lee were closed without advance warning which jammed up traffic for hours. Democrats feel the lanes might have been ordered closed as political payback to the town’s Democratic mayor for refusing to endorse Christie’s re-election.

In early January an email sent from Christie’s Deputy Chief of Staff Bridget Kelly to David Wildstein, the number-two man at the Port Authority stated “Time for some traffic problems in Fort Lee.”

Kelly and Wildstein were subsequently fired and Christie cut ties with his long time advisor and campaign strategist Bill Stepien. His top appointee to the Port Authority, Bill Baroni, was also fired.
