We traveled throughout the United States and never issued a single subpena. Neither did we ever attempt to crossexamine any witness. What constitutes migration? We have always had it in the United States. In the early days of this country we welcomed migration. Lincoln was a migrant from Kentucky and he always referred to how well the Ohio people took care of him. But when the depression came along all sorts of barriers are raised against human migration from State to State. I would like to say to you that everyone has a constitutional right in this country to move from one State to the other.
