New Jersey Gov. Chris Christie shakes hands as he leaves a prayer service in celebration of his inauguration at the New Hope Baptist Church on Tuesday, Jan. 21, 2014 in Newark. The celebrations to mark the start of Christie's second term could be tempered by investigations into traffic tie-ups that appear to have been ordered by his staff for political retribution and an allegation that his administration linked Superstorm Sandy aid to approval for a real estate project.
