Chris Christie's denial that he had prior knowledge of his staff closing lanes of the GW Bridge in order to punish the mayor of the town at the NJ end of it for not endorsing Christie, is wholly believable to me. I mean, even if you believe Christie is a bully and plays dirty ball with political enemies, what does that gain him? How does that punish the mayor of that town? It's a stupid way to play pay-back and Christie may be a lot of things, but stupid isn't one of them.
Yet the media continue to dig to try to find the smoking gun that links Christie to the closings.....which if found would sink his presidential ambitions completely. Obviously the media want badly to find confirmation because Christie is the lone republican that can challenge Hillary for the White House in 2016.
All that said, why don't the media hold Obama to the same standard of knowledge of, or at least awareness of, what those immediately under him are up to. He claimed ignorance over Fast and Furious, Benghazi, the Obamacare web-sight build-up and roll-out, the IRS-TEA Party scandal, etc.
The media let him claim ignorance at every turn. By his own admission, he's the most ignorant President we've ever had.
