(CNN) - The New Jersey Assembly announced it's launching a new investigation into the George Washington Bridge closings scandal.
Two of Governor Chris Christie's aides are accused of ordering lane closures at the nation's busiest bridge as political payback to the mayor of Fort Lee.
According to state assembly leadership, it's forming a new committee with subpoena power to investigate.
Christie held a lengthy news conference last week to say his aides kept him in the dark about the real reason for the closures.
On Thursday, he visited the mayor of Fort Lee.
And on Friday, a New Jersey State Assembly committee released more than 2,000 pages of documents on the issue.
State Assemblyman John Wisniewski, a Democrat, said they have yet to find any documents implicating Christie.
But he claims it "strains believability" that Christie didn't know about it.
The state assembly is led by Democrats, while Christie is a Republican.
