Washington (CNN) - Embattled New Jersey Gov. Chris Christie on Monday forcefully reiterated he knew nothing about lane closures at the George Washington Bridge last September before media reports appeared.
Christie, whose administration is under fire for suggestions top appointees orchestrated traffic jams at the foot of the bridge in Fort Lee to punish that town's mayor politically, said again that he "had nothing to do with this."
In a radio interview with New Jersey 101.5, Christie was asked to respond to a new allegation from a central figure in the scandal that "evidence exists" showing he was aware of the lane closings in real time over a work week last September, contradicting his recollection of events.
The allegation was made by David Wildstein, a former top Christie appointee at the Port Authority of New York and New Jersey, who is thought to have carried out the lane closures and has been subpoenaed by a state legislative committee for all documents and other materials on the matter.
But Christie, whose comments on Monday mirrored what he expressed at a January news conference, said he asked aides to investigate once he became aware of the traffic mess.
"I was told at the time that the Port Authority was engaged in a traffic study," Christie said, again reiterating past comments on the subject. "That's what I was told at the time."
