On "60 Minutes," Trump hinted that he might moonwalk away from some of his most radical promises on immigration, the issue that made him stand out from the crowd of Republican contenders. He still says he will build a wall on the Mexican border, but there "could be some fencing" instead of an actual wall in places. And he said that "we're going to make a determination" about the fate of millions of undocumented immigrants who have not committed crimes  sounding as if he knows his pledge to carry out mass deportation cannot be fulfilled.
