The U.S. attorney for New Jersey has issued a subpoena to a state legislative panel for all documents it has obtained through its investigation of September lane closures at the George Washington Bridge, the committee said Friday.
The panel's cochairs, Assemblyman John S. Wisniewski (D., Middlesex) and Senate Majority Leader Loretta Weinberg (D., Bergen), said in a statement that it "will comply fully with the request."
"This reaffirms our progress in uncovering important information about the apparent abuse of government power and threat to public safety," the statement said.
U.S. Attorney Paul Fishman's office is conducting a criminal investigation into the lane closures, allegedly orchestrated by then-associates of Republican Gov. Christie to exact political revenge against the Democratic mayor of Fort Lee, a Bergen County borough near the bridge.
A grand jury has taken testimony from at least one member of Christie's administration.
Rebekah Carmichael, a spokeswoman for the U.S. Attorney's Office, said she could not discuss the "specifics of ongoing investigations." News of the subpoena was first reported Friday morning by the Wall Street Journal.
The legislative committee has issued about 30 subpoenas and received thousands of documents about the lane closures. Next month, the committee is scheduled to take oral testimony from current and former members of the administration and officials at the Port Authority of New York and New Jersey, which operates the bridge.
Called to testify were Michael Drewniak, Christie's press secretary; Christina Genovese Renna, a former administration official; Patrick Foye, executive director of the Port Authority; and William "Pat" Schuber, a Christie-appointed commissioner at the Port Authority.
