Federal prosecutors in New Jersey have demanded to see documents from Gov. Chris Christie’s (R) re-election campaign and the state Republican Party in the investigation into the bridge scandal.

Mark Sheridan, an attorney with the law firm of Patton Boggs, told TPM on Thursday he is representing both groups that were subpoenaed and they intend to comply with the subpoenas. According to Sheridan, the subpoenas “all relate to the closure of lanes on the George Washington Bridge” and are returnable Feb. 5.

Rebekah Carmichael, a spokeswoman for the U.S. Attorney’s Office, told TPM, “Our office can neither confirm nor deny any specific investigative actions.” Sheridan did not immediately respond to a request for comment.

Christie’s re-election campaign has also been subpoenaed by a committee in the state legislature that is investigating the closures and other “concerns about abuse of government power.” Documents subpoenaed by the state Assembly committee last month indicating Christie’s former campaign manager, Bill Stepien, may have been involved in the closures. Christie subsequently asked Stepien to remove his name from the running to be chair of the state Republican Party.

Some Democrats have alleged the closures were ordered by Christie’s allies to retaliate against a mayor who declined to endorse him. On Saturday, the mayor of Hoboken, N.J. claimed Christie administration officials threatened to withhold Hurricane Sandy aid from her city unless she approved a real estate project.
