A wounded Chris Christie is working to move beyond the most challenging test of his political career.
But the New Jersey Republican governor's critics promise to keep probing a traffic scandal that rocked his administration this week and threatens to tarnish his national image ahead of the next presidential contest.
Christie's allies suggest the worst is behind him, although federal prosecutors are examining the case and thousands more internal documents are scheduled for release on Friday.
The governor fired a top aide and jettisoned his chief political adviser on Thursday. Documents released earlier in the week reveal that his administration may have intentionally caused a traffic jam on the George Washington Bridge to exact political retribution.
Christie adamantly denied any personal "knowledge or involvement" in the lane closures.
