Nah. I'm sure he was given the option to resign privately but he declined it. Critical thinking: All of these Congressmen who are not running for re-election- do you really think they were perfectly innocent angels who did no wrong? I REALLY doubt it.
Christopher just failed to see the writing on the wall and resign when he had a chance. I WOULD call him the first sacrificial lamb of many thousands though.
