The Republican governor said over and over that he knew nothing about the effort to shut down entrance lanes to the bridge in an apparent attempt to punish the Democratic Fort Lee Mayor Mark Sokolich for failing to endorse Christie's re-election bid.
"As I hoped and expected, Governor Christie was forthright, sincere, seriously embarrassed and unequivocally apologetic," Ken Langone, co-founder of Home Depot and a major Christie Wall Street supporter, told me in an email from Vietnam.
Other Wall Streeters who watched the presser said Christie performed well but that if any documents or interviews come out in the many ongoing investigations suggesting the governor did know something about the closures, his career is likely over.

"He didn't do too badly," said a top executive at one of the largest firms on Wall Street. "As long as it's all true."
Christie was as unequivocal as he could possibly be that he did nothing to direct the lane closures. But some questions remain.

Among them: How did Christie's appointee at the Port Authority, David Wildstein, know to shut down the lanes with only a single instruction from now-former Christie deputy chief of staff Bridget Anne Kelly? Some observers suggested the terse email exchange, in which Wildstein simply replied "got it," suggested it might not have been the first time this type of activity took place.
Others asked why Christie talked on Thursday about having a couple of sleepless nights when he claimed to have only learned of the damning emails on Wednesday? And why did Christie repeatedly say that there may indeed have been some kind of "traffic study" involved in the lane closures? Why is the governor clinging to that possible explanation when the true reason for the closures is now known? Are there documents suggesting someone tried to make the closures look like a traffic study after the fact?
