Oddly probably the biggest deportation event in US history was under the administration of Franklin Roosevelt. It was through a type of deportation known as internal deportation and over 200,000 American citizens were removed from their homes and sent to "internment camps" based solely on their ethnic background. They were never put on trial and most of them had their homes looted and their land taken away with no compensation.
That's what happens when xenophobia comes to town.
