TRENTON, N.J. — New Jersey Gov. Chris Christie maintained in an interview aired Monday that he has no recollection of any of his aides telling him about lane closures on the George Washington Bridge that were found to be a political retaliation plot.

Two of Christie’s former aides were convicted Friday of causing epic traffic jams near the nation’s busiest bridge, a plot that Christie called “one of the most abjectly stupid things I’ve ever seen.”

Bridget Kelly, Christie’s former deputy chief of staff, and Bill Baroni, an executive at the Port Authority of New York and New Jersey, were convicted of scheming with former Christie ally David Wildstein to punish a Democratic mayor for not endorsing Christie when he ran for re-election in 2013. Wildstein pleaded guilty.

Christie said that he could never figure out why aides would have retaliated.
