Trump recently took DACA off the negotiating table, announcing it in a tweet, citing a Fox News & Friends segment on 'caravans' of inbound immigrants: https://www.reuters.com/article/us-usa-immigration/trump-say... The President is watching this same garbage and making policy decisions based on it. Let that sink in for a moment.
If you watched the state of the union, you know that Trump made a proposal about DACA that was such a huge compromise to the left, that much of his base raised hell. The left refused that compromise, and refused again, when he asked for DACA and the wall to be addressed in the latest spending bill. Since he has twice been rebuffed on his compromises, he's going the other way. That seems reasonable to me.
I’m all for increased immigration and amnesty, but I’m not in support of open borders, so a compromise for increased border security sounded like good policy to me.
