Trump and his followers call that person a liar.
I heard Trump say in an interview, or a debate, maybe both, he would build a wall, deport 12 million people, and allow the good ones, the crime free ones to come back.
That is touchback amnesty.
Yes, that's been Trump's position since the end of July.
As a Trump supporter, I am banking on the fact that he is just kidding, and he really doesn't intend on letting any back in.
