Candidate Trump said he'd build that wall on the Mexican border and crackdown on "sanctuary" cities that harbor undocumented immigrants. As President, he's ordering implementation — despite massive cost, dispute about whether America will be safer — and civil liberties issues. He doesn't need any new legislation to build the wall, but lawyers are lining up to argue about withholding federal money from sanctuary cities. It's still not clear what's in store for "dreamers" — who were brought here illegally as children and don't know any other country.
