I see that you are a stranger to the truth.
I watched the video and his words seem so rehearsed it's hard to tell if he is actually in favor of deporting them. The illegal asks him "Will you deport us?" And he replies quickly, "No," blah blah blah, then reiterates about following the law, which would seem to contradict the "no." But then a journalist asks "Are you going to deport families?" to which he replies, "No, that's not what I said."
As far as I can tell, it is extraordinarily hard to know what he even said, which is pretty normal with Walker, actually.
