debra wong yang and randy mastro. miss yang has described christie as a very dear form and as a former bush appointed u.s. attorney just like chris christie. randy mastro was a deputy to former new york city governor rudy giuliani. he's now at least the eighth giuliani staffer to join team christie over the years. while gibson, dunn may be highlighting the documents and people they did have access to, the four most important people to getting to the bottom of the scandal were left out. mark sokolich, the mayor of ft. lee. former christie campaign manager bill stepien. christie appointee at the port authority, david wildstein, and bridget kelly, the former aide who ordered the traffic problems in ft. lee. all refuse to talk to gibson, dunn. here's what we currently know. the firm that chris christie hired to investigate his own administration cleared his administration of any wrongdoing. here's what we currently don't know. why traffic problems in ft. lee were ordered in the first place. joining me now, paul butler, pr
