"I'm not seeing anything really surprising or earth shattering -- you know, interesting things that may or may not mean something," Wisniewski said.
The committee sent subpoenas to 20 individuals and organizations, including close aides to Christie, along with the governor's office, and his re-election campaign. Some Democrats have alleged the closures, which caused days of paralyzing traffic in the city of Fort Lee, were ordered in retaliation against the mayor there, who refused to endorse Christie's re-election.
One thing Wisniewski said was clear from the documents he has seen so far is that the explanation officials initially gave for the closures is not plausible. Christie's top appointees at the Port Authority of New York and New Jersey, which oversees the bridge, originally attributed the closures to a traffic study.
"I don't think anybody should be actively trying to determine whether or not there was really a study about traffic," said Wisniewski. "It's pretty clear when you look at all the material that that was just, just not real."
