race. chris is playing long ball. if he's the first national figure to endorse someone who could become the republican nominee. might he have a place in trump administration if that were to ever happen. in new york, new jersey, the tri-state area, trump has a different identity beyond what we're seeing on the political campaign, that the relationship he has, christie and trump, may have something that can go much beyond this election season. definitely taking his knock, under criticism. the likelihood he would resign, short of being offered some other position is slim and none. >> interesting to see what happens. thank you for joining us. >> get much more buzz on donald trump and all of the presidential candidates coming up on nightly news 6:30 after
