Today on Midday: three perspectives on immigration. First, let’s consider what we might call Immigration Amnesia. It seems like a good way to describe politicians and others who speak derisively about immigrants -- when they themselves are, like everyone except for Indigenous people, descendants of people who came to this country from somewhere else. My first guest is Jennifer Mendelsohn.With her #resistancegenealogy project on Twitter, she has found a persuasive way to remind anti-immigrant Washington types of their own immigrant past. Mendelsohn is a Baltimore journalist. She is a former People magazine special correspondent and a columnist for Slate. Her work has also appeared in The New York Times, The Washington Post, The L.A. Times and many other places. She’s also an avid genealogist who serves on the board of the Jewish Genealogy Society of Maryland.
