DACA is a whole 'nother issue that didn't get much air time during the election...Trump never had too much to say about DACA even tho he was questioned on it a few times...
Trump has focused on the millions of 'illegal' aliens who are not connected to DACA...
DACA allows all relatives of these DACA recipients to move into the country...Parents, Grandparents, siblings, cousins, nieces and nephews; and of course when they are here legally, all of their relatives have a right to move in just as they did...In other words, anyone who has been born in Mexico will have the legal right to move here...Trump is fighting that thru the Supreme Court and so far has some success in limiting the population of Mexico from coming here...
Guess you forgot that he called it blatantly unconstitutional and he would end it.
