Poor Ann! She actually believes that Donald Trump would do a damn thing about illegal immigration. It is just a big applause line for Trump, which is why he keeps saying it. It is what he needs to say to close this deal.
In the unlikely event that he is the Republican nominee in the Fall, there will be different big applause lines, and Trump will say whatever he needs to say to close that, other, deal. Anything he said from June 2015 to June 2016 will be conveniently forgotten, just as everything he said before June 2015 has already been forgotten.
Ann has been played. But she is doubling down, because it is just too uncomfortable to admit that she was played. She should get over this. Donald Trump is a pro. There is no shame in getting played by a pro.
