The U.S. Attorney in New Jersey has issued subpoenas to Republican Gov. Chris Christie's reelection campaign and the New Jersey Republican State Committee, the latest development in the ongoing saga surrounding a traffic scandal involving aides to the governor.

An attorney for both Christie's campaign and the GOP state committee confirmed subpoenas were issued for documents. He said both entities intend to fully cooperate with prosecutors.

"We can confirm that the Christie  for Governor re-election campaign and the New Jersey Republican State Committee received subpoenas for documents from the U.S. Attorney’s office, in addition to the subpoena the campaign previously received from the state legislative committee," said Patton Boggs LLP attorney Mark Sheridan. "All three subpoenas focus on the closure of lanes on the George Washington Bridge.

Sheridan added the "campaign and the state party intend to cooperate with the U.S. Attorney’s office and the state legislative committee and will respond to the subpoenas accordingly."

The news was first reported by the Newark Star-Ledger.

Lawmakers and prosecutors are looking into the bridge scandal, in which aides to the governor snarled traffic leading from Fort Lee to the George Washington Bridge last year in an apparent act of political retribution. Christie has said he played no role in the incident and has dismissed aides at the center of the scandal.
